Description

Technical Field

[0001] The present invention relates to the technical field of production and manufacturing of optical devices, and in particular to a linear multi-channel array collimator adjustment device and a method for adjusting a collimator using the device. Background Art

[0002] With the development of data center optical module technology, the demand for miniaturized and arrayed optical communication devices has increased dramatically. Optical devices are becoming smaller and smaller. Multi-channel optical devices can achieve the transmission of multiple light beams within a single device, becoming an important development trend in optical devices. Since collimators are widely used in optical devices, with the widespread application of multi-channel optical devices, multi-channel collimators are also widely used in various optical devices.

[0003] At present, the multi-channel collimator has a multi-channel fiber array and a multi-channel lens array. When producing the multi-channel collimator, the multi-channel fiber array and the multi-channel lens array need to be adjusted to ensure that the optical fiber of each channel is facing the lens of the corresponding channel. At present, commercial array-type collimators mostly adopt a 3-channel or 6-channel design, which cannot meet the density requirements of multi-channel parallel transmission in co-packaged optical (CPO) devices. However, if the number of channels in the collimator is increased, the difficulty of adjusting the collimator will be greatly increased. Since the traditional multi-dimensional adjustment frame takes about 15 minutes to adjust the optical fiber and lens of a single channel, if a collimator with 18 channels, 36 channels or even more channels is adjusted, the adjustment cost will be very high, and it will also affect the production efficiency of the multi-channel collimator.

[0004] Patent application CN114063217A discloses a fixture for assembling a fiber array and a lens array. The fixture comprises multiple components, including a fixing plate, a clamping block, a slider, and a pressure block. However, the fixture primarily facilitates clamping and removal of the fiber array in both horizontal and vertical directions. It does not significantly improve the alignment between the fiber array and the lens array, and therefore cannot enhance the alignment efficiency of a multi-channel fiber array and lens array. Summary of the Invention

[0005] A first object of the present invention is to provide a linear multi-channel array collimator adjustment device capable of quickly realizing the alignment of a multi-channel optical fiber array with a lens array.

[0006] A second object of the present invention is to provide a method for adjusting a multi-channel collimator using the above-mentioned linear multi-channel array collimator adjustment device.

[0007] To achieve the first objective of the present invention, the linear multi-channel array collimator adjustment device provided by the present invention includes a fiber array clamp and a lens array clamp, the fiber array clamp having a first base, the first base being provided with a single-fiber collimator fixing groove and a multi-channel fiber array fixing position, the first base being further provided with a pressure cover, the pressure cover being used to fix the single-fiber collimator in the single-fiber collimator fixing groove and the multi-channel fiber array in the multi-channel fiber array fixing position; the lens array clamp having a second base, a pressure rod being hinged on one side of the second base, a gasket being clamped between the pressure rod and the second base, and a lens array fixing position being formed on the gasket; a reflector being provided on the second base, the reflector being arranged opposite to the gasket, and the lens array installed above the lens array fixing position facing the multi-channel fiber array.

[0008] As can be seen from the above scheme, when using the linear multi-channel array collimator adjustment device to adjust the collimator, first fix the single-fiber collimator and the multi-channel fiber array to the fiber array fixture. Then, by adjusting the positions of the fiber array fixture and the lens array fixture, the single-fiber collimator is directly opposite the reflector, and the light beam emitted by the single-fiber collimator can return along the original path after being reflected by the reflector. At this time, the bottom surface of the multi-channel fiber array is substantially perpendicular to the end surface of the reflector. Finally, the single-fiber collimator is removed, and the multi-channel fiber array is moved to a position directly opposite the center of the reflector, so that the lens array installed above the lens array fixing position is directly opposite the multi-channel fiber array, thereby ensuring that the lens arrays are aligned with each other.

[0009] It can be seen that when the linear multi-channel array collimator adjustment device of the present invention is used to adjust the collimator, the relative angle between the multi-channel optical fiber array and the lens array is calibrated by first adjusting the position of the single-fiber collimator and the reflector. Therefore, it is only necessary to adjust the relative distance, the upper and lower relative height, and the front and back relative position of the multi-channel optical fiber array and the lens array in three dimensions. This can greatly reduce the difficulty of accurate multi-channel adjustment, save adjustment time, and thus reduce the cost of workstation construction.

[0010] A preferred solution is that the pressure cover can slide relative to the first base, and one end of the pressure cover can abut against the multi-channel optical fiber array.

[0011] It can be seen that the pressure cover can slide relative to the first base. By adjusting the relative position between the pressure cover and the first base, the multi-channel optical fiber array can be limited, thereby ensuring that the pressure cover can reliably fix the single-fiber collimator and the multi-channel collimator array.

[0012] A further solution is that the gland is provided with a slide groove, the first base is provided with a plurality of positioning holes, and the screw passes through the slide groove and is screwed into one of the positioning holes.

[0013] It can be seen that, by cooperating with the screws and the plurality of positioning holes, the gland can be positioned at a plurality of gears, thereby achieving rapid and accurate positioning of the gland.

[0014] A further solution is that a hinge hole is provided in the middle of the pressure rod, a hinge is formed on the second base, and the hinge passes through the hinge hole; a gasket groove is provided on the second base near the reflector at the first end of the pressure rod, and the gasket is fixed in the gasket groove.

[0015] It can be seen that the pressure rod is hinged to the second base through the cooperation between the hinge shaft and the hinge shaft hole, which facilitates the rotation of the pressure rod and thereby realizes the clamping and loosening of the gasket.

[0016] A further solution is that the reflector and the gasket are arranged at an angle, and the angle between the reflector and the gasket is a preset acute angle.

[0017] It can be seen that the reflector has been fixed to the second base in advance, and the inclination angle of the reflector has also been set in advance, thereby reducing the difficulty of adjustment.

[0018] A further solution is that an elastic reset member is provided between the second base and the second end of the pressure rod, an elastic reset member installation groove is provided on the second base, and a part of the elastic reset member is installed in the elastic reset member installation groove.

[0019] It can be seen that the elastic reset member can enable the pressure rod to maintain clamping of the gasket, ensuring the reliability of the gasket clamping.

[0020] A further solution is that one side of the multi-channel optical fiber array presses against the single-fiber collimator.

[0021] A further solution is that a first threaded hole is provided on the first base, and the first base is fixed to the first adjustment frame through the first threaded hole; a second threaded hole is provided on the second base, and the second base is fixed to the second adjustment frame through the second threaded hole.

[0022] It can be seen that the optical fiber array fixture and the lens array fixture are fixed on the first adjustment frame and the second adjustment frame respectively. Therefore, by adjusting the positions of the first adjustment frame and the second adjustment frame, the relative position adjustment between the optical fiber array fixture and the lens array fixture can be achieved, thereby achieving the position adjustment between the multi-channel optical fiber array and the lens array.

[0023] To achieve the above-mentioned second purpose, the linear multi-channel array collimator adjustment method provided by the present invention is applied to the above-mentioned linear multi-channel array collimator adjustment device, the method including adjusting the position of the pressure cover so that the single-fiber collimator is fixed in the single-fiber collimator fixing groove, so that the multi-channel optical fiber array is fixed in the multi-channel optical fiber array fixing position; adjusting the position of the optical fiber array clamp and the lens array clamp so that the single-fiber collimator faces the reflector, and the light beam emitted by the single-fiber collimator can return to the original path after being reflected by the reflector; removing the single-fiber collimator and moving the multi-channel optical fiber array to a position facing the center of the reflector, so that the lens array installed above the lens array fixing position faces the multi-channel optical fiber array.

[0024] As can be seen from the above scheme, when adjusting the linear multi-channel collimator, the present invention first adjusts the position of the single-fiber collimator and the reflector so that the relative angle between the multi-channel fiber array and the lens array has been calibrated. Therefore, in the subsequent adjustment process, only the relative distance, the upper and lower relative height, and the front and back relative position of the multi-channel fiber array and the lens array need to be adjusted. This can greatly reduce the difficulty of accurate multi-channel adjustment, save adjustment time, and thus reduce the adjustment cost of the multi-channel collimator.

[0025] A preferred solution is that the first base is fixed on the first adjustment frame, and the second base is fixed on the second adjustment frame; adjusting the position of the optical fiber array fixture and the lens array fixture includes: adjusting the height, pitch angle and yaw angle of the first adjustment frame and / or the second adjustment frame.

[0026] It can be seen that by adjusting the height, pitch angle and yaw angle of the first adjustment frame and / or the second adjustment frame, the relative positions of the optical fiber array fixture and the lens array fixture can be quickly adjusted, thereby quickly adjusting the collimator.

[0042] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0043] The linear multi-channel array collimator adjustment device of the present invention is used to adjust a linear multi-channel collimator, which includes a multi-channel fiber array and a lens array, wherein the multi-channel fiber array includes a plurality of optical fibers, and the lens array includes a plurality of lenses, with one optical fiber corresponding to one lens. When adjusting the collimator, it is necessary to adjust the relative positions of the multi-channel fiber array and the lens array to ensure that each optical fiber is directly opposite to the corresponding lens. In addition, the collimator array adjusted by the present invention is arranged linearly, that is, the plurality of optical fibers in the multi-channel fiber array are arranged along a one-dimensional direction, and the plurality of lenses in the lens array are also arranged along a one-dimensional direction.

[0044] Linear multi-channel array collimator adjustment device embodiment:

[0045] See also Figure 1 and Figure 2 The linear multi-channel array collimator adjustment device of this embodiment comprises a fiber array fixture 10 and a lens array fixture 40, which are arranged close to each other. The fiber array fixture 10 is used to clamp the multi-channel fiber array 32, and the lens array fixture 40 is fixed with the lens array 62. The relative positions of the multi-channel fiber array 32 and the lens array 62 are adjusted by adjusting the relative positions of the fiber array fixture 10 and the lens array fixture 40.

[0046] See also Figures 3 to 5 The optical fiber array fixture 10 includes a first base 11 having two first threaded holes 12 formed therein. Each of the first threaded holes 12 has internal threads. The first base 11 is secured to the first adjustment frame via the two first threaded holes 12. For example, screws are passed through the first threaded holes 12 to secure the first base 11 to the first adjustment frame. The specific structure of the first adjustment frame will be described later.

[0047] The first base 11 is provided with a single fiber collimator fixing groove 16, see Figure 6 and Figure 7 The single-fiber collimator fixing groove 16 is V-shaped, and the cylindrical single-fiber collimator 31 is placed in the single-fiber collimator fixing groove 16. In addition, a multi-channel optical fiber array fixing position 19 is formed on the first base 11, and a multi-channel optical fiber array 32 is located on the multi-channel optical fiber array fixing position 19. The multi-channel optical fiber array 32 has an upper cover plate 18 and a lower cover plate 17, and multiple optical fibers 33 are clamped between the upper cover plate 18 and the lower cover plate 17.

[0048] The multi-channel optical fiber array 32 is located on one side of the single-fiber collimator fixing groove 16, for example, on the left side of the single-fiber collimator fixing groove 16. When the single-fiber collimator 31 is placed in the single-fiber collimator fixing groove 16, the multi-channel optical fiber array 32 presses the single-fiber collimator 31 from the left side, thereby fixing the single-fiber collimator 31 in the single-fiber collimator fixing groove 16.

[0049] The optical fiber array fixture 10 is also provided with a gland 20, which is located above the first base 11 and can slide relative to the first base 11. The gland 20 is provided with a slide groove 22, which is a through hole that penetrates the gland 20. The first base 11 is provided with three positioning holes 27, each of which has an internal thread. A screw 28 can pass through the slide groove 22 and screw into one of the positioning holes 27. After adjusting the position of the gland 20 relative to the first base 11, the screw 28 is passed through the slide groove 22 and screwed into one of the positioning holes 27 to secure the gland 20 to the first base 11.

[0050] In addition, a limiting portion 23 is formed at one end of the pressure cover 20 close to the multi-channel optical fiber array 32, see Figure 6 and Figure 7 A stepped surface 24 of the limiting portion 23 can abut against one side of the multi-channel optical fiber array 32, and a portion of the pressure cover 20 also presses against the top of the multi-channel optical fiber array 32. Therefore, the pressure cover 20 can limit the multi-channel optical fiber array 32 from both the top and left directions.

[0051] Because the other side of the multi-channel fiber array 32 also presses against the single-fiber collimator 31, when the gland 20 limits the position of the multi-channel fiber array 32, the multi-channel fiber array 32 also limits the position of the single-fiber collimator 31. Therefore, by adjusting the position of the gland 20, the single-fiber collimator 31 can be fixed in the single-fiber collimator fixing groove 16, and the multi-channel fiber array 32 can also be fixed in the multi-channel fiber array fixing position 19.

[0052] Furthermore, the single-fiber collimator fixing groove 16 is parallel to the fixing position of each optical fiber in the multi-channel optical fiber array 32. Therefore, after being limited by the pressure cover 20, the single-fiber collimator 31 and each optical fiber in the multi-channel optical fiber array 32 can be parallel to each other.

[0053] See also Figure 8 and Figure 9The lens array fixture 40 includes a second base 41, which is provided with two second threaded holes 42, each of which is provided with an internal thread. The second base 41 is fixed to the second adjustment frame via the two second threaded holes 42, for example, by screws passing through the second threaded holes 42 to secure the second base 41 to the second adjustment frame. Preferably, the first adjustment frame and the second adjustment frame have substantially the same structure and are mirror images.

[0054] A pressure rod 50 is provided on one side of the second base 41, and the pressure rod 50 is hinged on one side of the second base 41. Figure 10 and Figure 11 A hinge slot 46 is provided in the middle of the second base 41, and a hinge shaft 47 is provided in the hinge slot 46. A hinge hole 53 is provided in the middle of the pressure rod 50, and the hinge shaft 47 can pass through the hinge hole 53, so that the pressure rod 50 can rotate relative to the second base 41.

[0055] A pressure arm 51 is provided at one end of the pressure rod 50, and a protrusion 52 is provided at the end of the pressure arm 51. An extension arm 43 is provided at one end of the second base 41 close to the pressure arm 51, and a gasket groove 45 is formed on the side of the extension arm 43 close to the pressure arm 51, and the gasket 61 is fixed in the gasket groove 45. Preferably, the gasket 61 is opposite to the protrusion 52, and when the pressure rod 50 clamps the gasket 61, the protrusion 52 abuts on the surface of the gasket 61. In this way, the gasket 61 is clamped between the second base 41 and the pressure rod 50. A lens array fixing position is formed above the gasket 61, and the lens array 62 is fixed on the lens array fixing position. For example, the lens array 62 is fixed above the gasket 61 in advance using glue or the like.

[0056] A reflector 44 is provided on the second base 41. The reflector 44 is provided opposite to the gasket 61. Figure 10 It can be seen that the reflector 44 is fixed on the side opposite to the gasket groove 45 of the extension arm 43, so that the lens array 62 installed above the lens array fixing position is facing the reflector 44. In addition, the reflector 44 and the lens array 62 of this embodiment are not parallel to each other, but form a specific angle, such as 8°. The return loss of the collimator after adjustment can be reduced by setting the reflector 44 and the lens array 62 to an angle of 8°. Therefore, the reflector 44 is tilted relative to the gasket 61. In order to meet this requirement, the reflector 44 can be fixed on the extension arm 43 at an angle so that the angle between the gasket groove 45 and the reflector 44 is a preset acute angle, such as Figure 12 and Figure 13 Thus, the included angle between the reflector 44 and the spacer 61 is also a preset acute angle, so that the lens array 62 and the reflector 44 are tilted, and the included angle between the lens array 62 and the reflector 44 is 8°.

[0057] In addition, an elastic return member is disposed between the pressure rod 50 and the second base 41. In this embodiment, the elastic return member is a spring 72. An elastic return member mounting groove 71 is provided on the second base 41, and a portion of the spring 72 is mounted within the elastic return member mounting groove 71. Furthermore, a blind hole 54 is also provided on the pressure rod 50, and one end of the spring 72 is fixed within the blind hole 54. Therefore, the two ends of the spring 72 respectively abut the pressure rod 50 and the second base 41, and the spring 72 is disposed at the end away from the pressure arm 51. Thus, under the elastic force of the spring 72, the pressure arm 51 of the pressure rod 50 maintains pressure on the gasket 61, thereby clamping the gasket 61 between the pressure rod 50 and the second base 41.

[0058] Example of a linear multi-channel array collimator adjustment method:

[0059] The following combination Figure 14 The method for adjusting the linear multi-channel array collimator using the linear multi-channel array collimator adjustment device is introduced. First, perform step S1 to fix the first base on the first adjustment frame and the second base on the second adjustment frame. The structures of the first adjustment frame and the second adjustment frame of this embodiment are basically the same and are mirror-imaged. Figure 15 The first adjustment frame 80 is used as an example for description. The first adjustment frame 80 includes a third base 88, on which an adjustment assembly 81 is mounted. The adjustment assembly 81 can move relative to the third base 88 in multiple directions, such as vertically, forwardly, backwardly, and leftwardly. Furthermore, the adjustment assembly 81 can rotate relative to the third base 88, for example, to adjust the pitch and yaw angles of the adjustment assembly 81 relative to the third base 88.

[0060] The adjustment assembly 81 is provided with an adapter 82, and the optical fiber array fixture 10 is fixed to the adapter 82. For example, the adapter 82 is provided with two threaded holes, and screws are passed through the first threaded hole 12 on the first base 11 and the threaded holes on the adapter 82 to fix the optical fiber array fixture 10 to the adapter 82.

[0061] In addition, the first adjustment frame 80 is provided with a height adjustment knob 83, a left and right adjustment knob 84, a front and back adjustment knob 85, a yaw angle adjustment knob 86 and a pitch angle adjustment knob 87. The height adjustment knob 83, the left and right adjustment knob 84, the front and back adjustment knob 85, the yaw angle adjustment knob 86 and the pitch angle adjustment knob 87 can be used to change the positional relationship between the adjustment component 81 and the third base 88.

[0062] The structure of the second adjustment frame is substantially the same as that of the first adjustment frame 80 , but they are in a mirror image relationship, so that the operator can operate the first adjustment frame with his left hand and the second adjustment frame with his right hand.

[0063] Fix the first base on the first adjustment frame 80, and fix the second base on the second adjustment frame. It is necessary to reasonably place the positions of the first adjustment frame and the second adjustment frame so that the position relationship between the optical fiber array fixture and the lens array fixture is as follows: Figure 1 and Figure 2 As shown, the single-fiber collimator and the multi-channel optical fiber array can both face the reflector, and the lens array is located at one end of the multi-channel optical fiber array close to the reflector.

[0064] Then, step S2 is performed to fix the single-fiber collimator in the single-fiber collimator fixing groove, and place the multi-channel optical fiber array in the multi-channel optical fiber array fixing position, and by adjusting the position of the pressure cover, the single-fiber collimator is fixed in the single-fiber collimator fixing groove, and the multi-channel optical fiber array is fixed in the multi-channel optical fiber array fixing position.

[0065] Next, step S3 is performed to adjust the positions of the fiber array fixture and the lens array fixture. Specifically, the height, pitch angle, and yaw angle of the first adjustment frame and / or the second adjustment frame are adjusted so that the light beam emitted from the single-fiber collimator can return along its original path. Because the single-fiber collimator is parallel to each optical fiber in the multi-channel fiber array, the bottom surface of the multi-channel fiber array is essentially perpendicular to the end face of the reflector.

[0066] Then, step S4 is performed to remove the single-fiber collimator and move the multi-channel fiber array to a position facing the center of the reflector. In this way, the lens array installed above the lens array fixing position faces the multi-channel fiber array, thus ensuring that the lens arrays are aligned with each other.

[0067] Finally, step S5 is executed to fine-tune the positions of the multi-channel optical fiber array and the lens array. Specifically, the relative distance, relative height, and relative position between the multi-channel optical fiber array and the lens array are adjusted.

[0068] It can be seen that when the linear multi-channel array collimator adjustment device is used to adjust the collimator, the relative angle between the multi-channel fiber array and the lens array has been calibrated by first adjusting the position of the single-fiber collimator and the reflector, that is, the yaw angle and the pitch angle have been calibrated in step S3. Therefore, in step S4, only the relative distance, the upper and lower relative height, and the front and back relative position of the multi-channel fiber array and the lens array need to be adjusted. Since step S3 uses a single-fiber collimator to calibrate the yaw angle and the pitch angle, the calibration is less difficult and the process complexity is low. Therefore, the application of the method of the present invention can greatly reduce the difficulty of accurate multi-channel adjustment, save adjustment time, thereby reducing the cost of station construction, and thus reducing the production cost of the multi-channel collimator.

[0069] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
