[0001] This application relates to the field of wavelength division multiplexing (WDM) technology, and in particular to a coupling method, apparatus, system, and medium for a WDM component. Background Technology
[0002] Wavelength division multiplexing (WDM) is a technique that combines two or more different wavelengths of optical carrier signals at the transmitting end using a multiplexer and transmits them through the same optical fiber. At the receiving end, a demultiplexer separates the optical carrier signals of various wavelengths, and then the optical receiver performs further processing to recover the original signals. This technique of simultaneously transmitting two or more different wavelength optical signals in the same optical fiber is called wavelength division multiplexing.
[0003] Wavelength division multiplexing (WDM) optical emission modules typically consist of multiple laser chips of different wavelengths, lens assemblies, and a main control circuit board. The lens assembly includes a lens body and multiple filters corresponding to the laser chips. During assembly, the lens assembly must be coupled to the laser chips on the circuit board. However, due to the large number of laser chips in the optical emission module and the relatively low coupling accuracy, ensuring optimal optical power for each laser chip and improving the coupling accuracy between the lens assembly and the laser chips are pressing issues that need to be addressed in this field. Summary of the Invention

Any one of the multiple optical power measurement values is the optical power measurement value of the beam emitted by the corresponding laser chip after passing through the lens assembly.
[0008] If each of the plurality of optical power measurements does not meet the optical power range associated with its corresponding laser chip, then the lens assembly is controlled to adjust from the initial orientation to the target orientation so that the lens assembly and the plurality of laser chips are in a coupled state.
[0009] When the lens assembly is positioned at the target location, the measured optical power of the light beam emitted by each of the plurality of laser chips after passing through the lens assembly meets the optical power range associated with it.
[0010] A second aspect of this application provides a coupling device for a wavelength division multiplexing (WDM) component, comprising:

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0024] To address the challenges in related technologies such as the difficulty in ensuring optimal optical power values for each laser chip and low coupling accuracy of the lens assembly, the first embodiment of this application provides a coupling method for a wavelength division multiplexing (WDM) assembly, applied to a WDM assembly coupling system. The WDM assembly coupling system includes a lens assembly and multiple (two or more) laser chips; such as Figure 1 This is a basic flowchart illustrating the coupling method of the wavelength division multiplexing (WDM) component provided in this embodiment. The coupling method of the WDM component includes the following steps:
[0025] Step 101: Control multiple laser chips to emit beams to the lens assembly respectively.
[0026] Specifically, in this embodiment, the lens assembly includes a lens body and a filter, wherein the filter corresponds to a laser chip, and the number and position of the filter can be adjusted accordingly based on the number and position of the laser chips. In this embodiment, the laser chips are pre-installed on the board, and each laser chip can be controlled to emit a beam of light to the lens assembly by connecting a power source.
[0027] Step 102: Obtain multiple optical power measurement values. The multiple optical power measurement values correspond to multiple laser chips. Any one of the multiple optical power measurement values is the optical power measurement value of the beam emitted by the corresponding laser chip after passing through the lens assembly.
[0028] Specifically, in this embodiment, in order to improve the coupling accuracy between the lens assembly and the laser chip and optimize the optical power of each laser chip, this embodiment refers to the optical power measurement values of each laser chip to determine the relationship between the lens assembly and the laser chip. In this embodiment, the multiple optical power measurement values correspond one-to-one with the multiple laser chips.
[0029] In some embodiments of this example, the lens assembly includes multiple filters, each corresponding to one of the multiple laser chips. Before acquiring multiple optical power measurements, the method further includes: acquiring the azimuth of the emission point of each laser chip; controlling the lens assembly to adjust to a light-focusing azimuth; wherein, when the lens assembly is in the light-focusing azimuth, each filter is aligned with the emission point of its corresponding laser chip. In possible implementations, the multiple filters and the multiple laser chips have a one-to-one correspondence.
[0030] Specifically, in this embodiment, when the onboard carrying the laser chips is powered on, each laser chip will emit its own light. At this time, the position of the light-emitting point of the laser chip can be obtained, so as to adjust the lens body of the lens assembly to align with the light-emitting point, thereby focusing the light. Then, each beam can pass through the corresponding filter and reach the detection component to measure the optical power, so as to obtain the optical power measurement value of each laser chip.
[0031] Furthermore, in some embodiments of this example, obtaining multiple optical power measurement values includes: when multiple light beams emitted from the lens assembly are received, calculating the optical power values of the multiple light beams based on a preset optical power meter to obtain multiple optical power measurement values.
[0032] Specifically, in this embodiment, an optical fiber is connected to the optical fiber interface of the lens assembly, and the other end of the optical fiber is connected to a detection component for monitoring optical power, such as an optical power meter. The optical power measurement value of each laser chip can be obtained by measuring with the optical power meter. The number of optical power meters can be one or more, and can be designed according to actual needs, and is not limited here.
[0033] In other embodiments of this example, if a preset number of optical power measurements among multiple optical power measurements satisfy the optical power range associated with their corresponding laser chips, then the lens assembly and the multiple laser chips are in a coupled state.
[0034] Specifically, in this embodiment, after detecting the optical power measurement values of each laser chip, the optical power range corresponding to each laser chip is obtained. Each optical power measurement value is matched with its corresponding optical power range, and the total number of optical power measurement values that conform to the optical power range is counted. When the total number reaches a preset threshold, it is determined that the current position of the lens assembly and the laser chip is in a coupled state. In addition, in order to reduce detection errors and improve coupling accuracy, the laser chip identifiers corresponding to optical power measurement values that conform to the optical power range can be further limited. For example, among all the laser chips corresponding to optical power measurement values that conform to the optical power range, there must be a target laser chip corresponding to the filter farthest from the fiber optic interface. That is, when the optical power measurement value corresponding to the target laser chip conforms to the optical power range, the optical power measurement values corresponding to laser chips at other positions are also relatively good. At this time, the coupling accuracy between the lens assembly and the laser chip can also meet the requirements.
[0035] Step 103: If each of the multiple optical power measurements does not meet the optical power range associated with its corresponding laser chip, then control the lens assembly to adjust from the initial orientation to the target orientation so that the lens assembly and the multiple laser chips are in a coupled state.
[0036] Specifically, in this embodiment, the initial orientation of the lens includes direction and position. When the lens assembly is in the target orientation, the optical power measurement value of the beam emitted by each of the multiple laser chips after passing through the lens assembly meets the optical power range associated with the corresponding laser chip. Specifically, when it is detected that all optical power measurements do not meet the optical power range, the lens assembly is controlled to perform translational adjustment, rotational adjustment, or a combination of translation and rotational adjustment to couple the lens assembly with the laser chip. When the positions of the lens assembly and the laser chip meet the requirements (i.e., aligned), the lens assembly and the laser chip are in a coupled state. At this time, the lens assembly and the laser chip can closely cooperate and influence each other to achieve signal transmission. The target orientation of the lens assembly can be determined. In this case, the lens assembly can be controlled to adjust to the target orientation according to a preset orientation adjustment index. For example, if the initial orientation is (0, 0, 0) and the target orientation is (0, 0, 5), the lens assembly can be controlled to move upwards to the target orientation multiple times in 1µm adjustment units, or move 5µm at a time to directly reach the target orientation.
[0037] In some embodiments of this example, before adjusting the lens assembly from the initial orientation to the target orientation, the method further includes: obtaining the optical power reference value of any one of the multiple laser chips; calculating the product of the optical power reference value and a preset parameter value to obtain the optical power range associated with any one laser chip.
[0038] Specifically, in this embodiment, the bare optical power of laser chips with different wavelengths is different, and the emitted power obtained after passing through filters located at different positions is also different. Since laser beams always experience losses during propagation, in practical use, the optimal optical power can be determined as long as the optical power value reaches a certain range, without requiring the measured value to reach the bare optical power. The optical power range corresponding to each laser chip can be calculated from the bare optical power in the chip specifications and a set ratio value. For example, the bare optical power of the laser chip corresponding to the filter farthest from the fiber optic interface is 1.5MW, and the set ratio value is 50% to 80%, then the optical power range is 0.6 to 1.2MW.
[0039] In other embodiments of this example, controlling the lens assembly to adjust from an initial azimuth to a target azimuth includes: comparing multiple optical power measurements with their corresponding preset optical power thresholds to obtain multiple comparison results; determining an initial azimuth adjustment index type based on at least one of the multiple comparison results; determining a corresponding azimuth adjustment strategy based on the initial azimuth adjustment index type; wherein the azimuth adjustment strategy includes multiple azimuth adjustment indices, and the types of azimuth adjustment indices include translation adjustment indices and / or rotation adjustment indices; controlling the lens assembly to adjust from the initial azimuth to the target azimuth with reference to the azimuth adjustment strategy; wherein the initial azimuth is the light focusing azimuth. It should be understood that each laser chip corresponds to a preset optical power threshold, i.e., there are multiple preset optical power thresholds; multiple preset optical power thresholds correspond to multiple laser chips, and multiple optical power measurements also correspond to multiple laser chips. Comparing the multiple optical power measurements with their corresponding preset optical power thresholds is equivalent to comparing the optical power measurement value corresponding to each laser chip with its preset optical power threshold. Furthermore, the preset optical power thresholds corresponding to each laser chip can be the same or different.
[0040] Specifically, in this embodiment, after acquiring the optical power measurement value, it can be compared with a preset optical power threshold, and the initial orientation adjustment index type can be determined based on the comparison result. A corresponding orientation adjustment strategy can then be determined based on the initial orientation adjustment index type. When the target orientation is not determined, the orientation adjustment strategy can be a pre-set set of orientation cyclic adjustment schemes, such as sequentially adjusting the X-axis, Y-axis, and Z-axis directions, then rotating, and continuously cycling to determine the target orientation. For example, if the initial orientation adjustment index type is determined to be a translation adjustment index, then the next adjustment index type is determined to be a translation adjustment index, that is, the lens assembly is sequentially controlled to perform rotation and translation operations. The rotation operation in one cycle can be multiple times. The translation adjustment index can be a preset value, such as 1µm, and the rotation adjustment index can also be a preset value, such as 1°. Finally, the lens assembly is adjusted to reach the target orientation based on multiple orientation adjustment indices, so that the lens assembly and the laser chip meet the coupling conditions.
[0041] Further, in some embodiments of this example, determining the initial orientation adjustment index type based on at least one of multiple comparison results includes: obtaining the target comparison result corresponding to the target laser chip; wherein the target laser chip is the laser chip corresponding to the filter farthest from the fiber optic interface in the lens assembly; when the target comparison result is a first comparison result where the optical power measurement value is less than the optical power threshold, the initial orientation adjustment index type is determined to be a translation adjustment index; the target comparison result is the comparison result corresponding to the target laser chip among the multiple comparison results, and the target laser chip is the laser chip corresponding to the filter farthest from the fiber optic interface in the lens assembly; when the target comparison result is a second comparison result where the optical power measurement value is greater than the optical power threshold, the initial movement operation type is determined to be a rotation adjustment index.
[0042] Specifically, in this embodiment, to improve the adjustment effect, the initial orientation adjustment index type can be determined based on the comparison between the measured optical power value corresponding to the reference laser chip and the preset optical power threshold. The reference laser chip can be the laser chip corresponding to the filter farthest from the fiber optic interface in the lens assembly. When the optical power value is greater than the preset optical power threshold, it can be determined that the measured optical power value is close to the optical power range, and a fine-tuning operation of the angle can be performed without moving the position. For example, if the measured optical power value corresponding to a certain laser chip is 0.5MW, which is greater than the optical power threshold of 0.4MW, the initial orientation adjustment index type is determined to be a rotation adjustment index. When the measured optical power value is less than the preset optical power threshold, the initial orientation adjustment index type is determined to be a translation adjustment index.
[0043] Based on the technical solution of the above embodiments of this application, the laser chip is controlled to emit a light beam to the lens assembly; the optical power measurement value corresponding to the light beam after passing through the lens assembly is obtained; if all optical power measurement values do not meet the optical power range associated with the corresponding laser chip, the lens assembly is controlled to adjust from the initial orientation to the target orientation so that the lens assembly and the laser chip are in a coupled state; when the lens assembly is in the target orientation, all optical power measurement values meet the optical power range associated with the corresponding laser chip. Through the implementation of the solution of this application, when it is determined that the optical power measurement value of each laser chip does not meet the preset optical power range, the lens assembly is adjusted according to multiple orientation adjustment indicators. When the lens assembly reaches the target orientation, it can be ensured that the optical power value of each laser chip reaches the optimal value, and the coupling accuracy between the lens assembly and the laser chip meets the requirements. This allows the energy of light of different wavelengths entering the optical fiber for transmission to meet the performance requirements, thereby improving the performance of the wavelength division multiplexing device.

[0047] The second control module 203 is used to control the lens assembly to adjust from the initial orientation to the target orientation if each of the multiple optical power measurement values does not meet the optical power range associated with its corresponding laser chip, so that the lens assembly and the multiple laser chips are in a coupled state; wherein, when the lens assembly is in the target orientation, the optical power measurement value of the beam emitted by each of the multiple laser chips after passing through the lens assembly meets the optical power range associated with the corresponding laser chip.
[0048] In some embodiments of this example, before the second control module adjusts the control lens assembly from the initial orientation to the target orientation, it is also used to obtain the optical power reference value of any one of the multiple laser chips; calculate the product of the optical power reference value and the preset parameter value to obtain the optical power range associated with any one laser chip.

[0051] Furthermore, in some embodiments of this example, when the second control module performs the step of determining the initial azimuth adjustment index type based on at least one of the multiple comparison results, it is further configured to determine the initial azimuth adjustment index type as a translation adjustment index when the target comparison result is a first comparison result where the optical power measurement value is less than the optical power threshold; the target comparison result is the comparison result corresponding to the target laser chip among the multiple comparison results, and the target laser chip is the laser chip corresponding to the filter farthest from the optical fiber interface in the lens assembly; when the target comparison result is a second comparison result where the optical power measurement value is greater than the optical power threshold, it determines the initial movement operation type as a rotation adjustment index.
[0052] In some embodiments of this example, after acquiring multiple optical power measurement values, the acquisition module is further configured to determine that the lens assembly and the multiple laser chips are in a coupled state if a preset number of optical power measurement values among the multiple optical power measurement values meet the optical power range associated with their corresponding laser chips.

Through the implementation of the solution of this application, when it is determined that the optical power measurement value of each laser chip does not meet the preset optical power range, the lens assembly is adjusted according to multiple azimuth adjustment indicators. When the lens assembly reaches the target azimuth, it can be ensured that the optical power value of each laser chip reaches the optimal level, and the coupling accuracy between the lens assembly and the laser chip meets the requirements.
