Description

Technical Field

[0001] This utility model relates to the field of fiber optic array technology, and in particular to an integrated two-dimensional fiber optic array module. Background Technology

[0002] Fiber optic arrays are a key component of optical fiber communication. Two-dimensional fiber optic arrays can achieve output and input at any point in an M×N array, providing a foundation for spatial routing. However, existing fiber optic arrays typically use monocrystalline silicon as the fiber fixing substrate, which results in high manufacturing costs. Furthermore, a separate guide hole array is required, which is then combined with the monocrystalline silicon substrate for fiber threading, making the process cumbersome. Additionally, the accuracy of the correspondence between the guide hole array and the monocrystalline silicon substrate affects the fiber's pointing accuracy. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated two-dimensional fiber optic array module, which has the advantages of reducing manufacturing costs and simplifying the operation process.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] According to embodiments of this disclosure, an integrated two-dimensional fiber optic array module is provided, comprising:

[0006] A fixed base is provided with an assembly groove;

[0007] An optical fiber fixing substrate is embedded and fixed within the assembly slot. The optical fiber fixing substrate is made of glass material using laser processing. The optical fiber fixing substrate has multiple through-holes arranged in an array, and a guide port is provided on one side of each optical fiber fixing hole; and...

[0008] An optical fiber assembly includes multiple optical fiber bundles, the front ends of which pass through the guide port into the optical fiber fixing hole, and the guide port and the optical fiber fixing hole are filled with an adhesive layer to fix the optical fiber bundles.

[0009] To achieve the above technical solution, the existing multilayer monocrystalline silicon substrate is replaced with an optical fiber fixing substrate made of glass material. On the one hand, the manufacturing process is simpler and the processing and assembly process is more efficient. On the other hand, it can eliminate the corresponding accuracy error that occurs after the assembly of multilayer monocrystalline silicon substrates, thus improving the optical fiber pointing accuracy. Furthermore, the optical fiber fixing substrate is formed by laser processing, which makes the processing more convenient. At the same time, by setting a guide port instead of the existing guide hole array, the integrated structure is easier to process and does not require reassembly, making the operation simpler.

[0010] In some exemplary embodiments, the fiber optic fixing hole is one of a circle, a semi-circle, a square, a triangle, or a polygon.

[0011] In some exemplary embodiments, the guide port is a conical or stepped hole.

[0012] To achieve the above technical solution, the shape of the fiber optic fixing hole and the form of the guide port can be selected as needed.

[0013] In some exemplary embodiments, the stripping length of the fiber bundle at its front end is greater than the thickness of the fiber fixing substrate.

[0014] To achieve the above technical solution, sufficient assembly length must be left at the front end of the optical fiber.

[0015] In some exemplary embodiments, the assembly slot is a stepped slot. After the optical fiber fixing substrate is embedded and fixed in the assembly slot, one side of it is in contact with the assembly slot and the other side is flush with the surface of the fixing base. The guide port is located inside the assembly slot.

[0016] The above technical solution enables accurate installation of the fiber optic fixing substrate.

[0017] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0018] This utility model provides an integrated two-dimensional fiber optic array module, comprising: a fixed base with an assembly slot; a fiber optic fixing substrate fixed within the assembly slot, the fiber optic fixing substrate being made of glass material using laser processing, the fiber optic fixing substrate having multiple through-holes arranged in an array, and a guide port on one side of each fiber optic fixing hole; and a fiber optic group comprising multiple fiber bundles, the front ends of each fiber bundle passing through the guide port into the fiber optic fixing hole, and a bonding layer filling the guide port and the fiber optic fixing hole to fix the fiber bundles. By using a fiber optic fixing substrate made of glass material instead of the existing multilayer monocrystalline silicon substrate, the manufacturing process is simplified, resulting in higher production efficiency. Furthermore, it eliminates the corresponding accuracy errors that occur after assembling multilayer monocrystalline silicon substrates, improving fiber pointing accuracy. The laser processing of the fiber optic fixing substrate also makes the processing more convenient. Simultaneously, by using a guide port instead of the existing guide hole array, the integrated structure is easier to process and requires no reassembly, simplifying operation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1 to 10 As shown, this utility model provides an integrated two-dimensional fiber optic array module, including: a fixing base 10, on which an assembly slot 11 is provided; a fiber optic fixing substrate 20, which is fixedly embedded in the assembly slot 11, the fiber optic fixing substrate 20 being made of glass material by laser processing, the fiber optic fixing substrate 20 having a plurality of through-holes 21 arranged in an array, and a guide port 22 being provided on one side of the fiber optic fixing hole 21; and a fiber optic group 30, the fiber optic group 30 including a plurality of fiber bundles 31, the front end of the fiber bundle 31 passing through the guide port 22 into the fiber fixing hole 21, and the guide port 22 and the fiber fixing hole 21 being filled with an adhesive layer 23 to fix the fiber bundle 31.

[0033] Specifically, the fixing base 10 and the optical fiber fixing substrate 20 can be fixed by adhesive bonding, and the assembly groove 11 is a stepped groove. After the optical fiber fixing substrate 20 is snapped into the assembly groove 11, one side of it is in contact with the assembly groove 11 and the other side is flush with the surface of the fixing base 10. The guide port 22 is located inside the assembly groove 11, thereby enabling the accurate installation of the optical fiber fixing substrate 20.

[0034] The fiber optic fixing hole 21 can be one of the following shapes: circular, semi-circular, square, triangular, or polygonal. Figures 2 to 5 As shown, Figure 2 A schematic diagram showing that the optical fiber fixing hole 21 is circular is shown. Figure 3 A schematic diagram showing that the optical fiber fixing hole 21 is square is shown. Figure 4 A schematic diagram showing that the fiber optic fixing hole 21 is semi-circular is shown. Figure 5 The diagram shows a triangular optical fiber fixing hole 21; while the guide port 22 can be configured as a conical or stepped hole, such as... Figure 6 and Figure 7 As shown, Figure 6 The diagram shows a structure where the guide port 22 is a tapered hole. Figure 7 The diagram shows a stepped hole-shaped guide port 22. In practical applications, the thickness of the fiber fixing substrate 20, the shape of the fiber fixing hole 21, and the form of the guide port 22 can be selected as needed.

[0035] During assembly, it is necessary to ensure that the stripped length of the fiber bundle 31 is greater than the thickness of the fiber fixing substrate 20, so as to ensure that the fiber bundle front end has sufficient assembly length. First, the fiber fixing substrate 20 is inserted into the assembly slot 11, with one side of the guide port 22 facing inward. Then, a specific tool is used to clamp the fiber bundle 31. The fiber bundle 31 passes through the guide port 22 into the fiber fixing hole 21 until the stripped position is completely inserted into the guide port 22. After the fiber bundle 31 is inserted, glue is applied to the fiber tail. Due to the capillary effect, the glue is drawn into the fiber fixing hole 21 and fills the fiber fixing hole 21. The glue is pre-cured to prevent the fiber bundle 31 from breaking or falling off due to shaking. After all channels are threaded, the glue is cured to form a glue layer 23. After curing, grinding and polishing are performed to obtain the two-dimensional fiber array module.

[0036] By replacing the existing multilayer monocrystalline silicon substrate with a glass fiber fixing substrate 20, the manufacturing process is simplified, resulting in higher production efficiency. Furthermore, it eliminates the accuracy errors that occur after assembling multilayer monocrystalline silicon substrates, thus improving fiber pointing accuracy. Figure 10 As shown, the angle θ represents the pointing accuracy; the fiber fixing substrate 20 is formed by laser processing, which makes the processing more convenient. At the same time, by setting the guide port 22 to replace the existing guide hole array, the integrated structure is easier to process and does not require reassembly, making the operation simpler.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
