[0001] The present disclosure relates to a photoelectric efficiency adjustment method and a photoelectric efficiency adjustment system, and in particular to a photoelectric efficiency adjustment method and a photoelectric efficiency adjustment system applied to a light-borne millimeter-wave antenna device. Background Art

[0002] As mobile communications become more and more closely integrated into daily life, the fifth-generation mobile communication technology (5G) has become an important development project. In order to meet the needs of 5G for high-speed data transmission, the optical millimeter wave (mmW-over-Fiber) centralized radio access network (C-RAN) based on optical fiber communication is the future development trend.

[0003] Optical millimeter wave antennas use silicon photonics technology to integrate passive integrated optical elements, optoelectronic conversion elements, and millimeter wave array antennas, and therefore require complex RF circuits and high-speed analog optoelectronic conversion interfaces. However, the existing efficiency adjustment methods for optical millimeter wave antennas mostly independently adjust the antenna path loss efficiency and the optical coupling efficiency of single-mode optical fibers. Therefore, a lot of time is required to clarify the loss of each path, resulting in a complicated production and testing process and high overall costs, which ultimately leads to poor optoelectronic conversion efficiency of optical millimeter wave antennas. Therefore, how to adjust and optimize the optoelectronic conversion efficiency of optical millimeter wave antennas has become an important issue. Summary of the invention

[0004] Therefore, the purpose of the present disclosure is to provide a photoelectric efficiency adjustment method and a photoelectric efficiency adjustment system. The difference between the method and the existing efficiency adjustment method is that the optical fiber edge coupling efficiency can be immediately adjusted and the adjustment mechanism of the line loss efficiency can be confirmed at the same time, thereby reducing the production test schedule, reducing the test cost, and achieving the optimization of the photoelectric efficiency.

[0005] According to an embodiment of the method implementation of the present disclosure, a photoelectric efficiency adjustment method is provided, which includes the following steps: a host computer controls a measuring device to provide a first input signal to an optical millimeter wave antenna device, and the first input signal is passed through a first loop formed by an electronic chip to generate a first output signal, and then a first conversion efficiency corresponding to the first loop is calculated based on the first input signal and the first output signal; a host computer controls a measuring device to provide a second input signal to the optical millimeter wave antenna device, and the second input signal is passed through a second loop formed by an electronic chip, a photonic chip and an optical fiber array to generate a second output signal, and then a second conversion efficiency corresponding to the second loop is calculated based on the second input signal and the second output signal; and the host computer adjusts a position where the optical fiber array is coupled to the photonic chip to change the second conversion efficiency. When the second conversion efficiency approaches the first conversion efficiency, the optical fiber array is fixed to the photonic chip.

[0006] According to one embodiment of the structural implementation of the present disclosure, a photoelectric efficiency adjustment system is provided, which includes a measuring device and a host computer. The measuring device is used to couple a light-borne millimeter wave antenna device. The light-borne millimeter wave antenna device includes an electronic chip, a photonic chip and an optical fiber array, the photonic chip is coupled to the electronic chip, and the optical fiber array is coupled to the photonic chip. The host computer is connected to the measuring device and is used to control the measuring device to provide a first input signal and a second input signal to the light-borne millimeter wave antenna device. The first input signal generates a first output signal after passing through a first loop formed by the electronic chip, and the second input signal generates a second output signal after passing through a second loop formed by the electronic chip, the photonic chip and the optical fiber array. The measuring device calculates a first conversion efficiency corresponding to the first loop based on the first input signal and the first output signal, and calculates a second conversion efficiency corresponding to the second loop based on the second input signal and the second output signal. The host computer adjusts a position where the optical fiber array is coupled to the photonic chip, thereby changing the second conversion efficiency. When the second conversion efficiency approaches the first conversion efficiency, the optical fiber array is fixed to the photonic chip. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] See also Figure 1 , Figure 1 FIG. 1 is a schematic diagram showing a photoelectric efficiency adjustment system 100 according to a first embodiment of the present disclosure applied to a millimeter-wave antenna device 200 . The photoelectric efficiency adjustment system 100 includes a measuring device 110 and a host computer 120 .

[0047] The measuring device 110 is used to couple with the optical millimeter wave antenna device 200. The optical millimeter wave antenna device 200 comprises an electronic chip 210, a photonic chip 220 and an optical fiber array 230. The electronic chip 210 is connected to the measuring device 110, the photonic chip 220 is coupled to the electronic chip 210, and the optical fiber array 230 is coupled to the photonic chip 220.

[0048] The host computer 120 is connected to the measuring device 110 by signal, and is used to control the measuring device 110 to provide the first input signal Sin_1 and the second input signal Sin_2 to the optical millimeter wave antenna device 200. The first input signal Sin_1 generates a first output signal Sout_1 after passing through a first loop formed by the electronic chip 210. The second input signal Sin_2 generates a second output signal Sout_2 after passing through a second loop formed by the electronic chip 210, the photonic chip 220, and the optical fiber array 230. The measuring device 110 calculates and generates a first conversion efficiency corresponding to the first loop according to the first input signal Sin_1 and the first output signal Sout_1, and calculates and generates a second conversion efficiency corresponding to the second loop according to the second input signal Sin_2 and the second output signal Sout_2, and the measuring device 110 transmits the first conversion efficiency and the second conversion efficiency back to the host computer 120.

[0049] In some embodiments, the measuring device 110 may be, but is not limited to, a network analyzer, or other suitable signal measuring devices. The host computer 120 may be, but is not limited to, a computer, or other suitable controllers. The electronic chip 210 in the optical millimeter wave antenna device 200 may be, but is not limited to, a millimeter wave radio frequency chip, or other suitable radio frequency integrated circuits (RFIC), and the photonic chip 220 may be, but is not limited to, a silicon photonic chip or other suitable photonic integrated circuits (PIC).

[0050] In some embodiments, the optoelectronic efficiency adaptation system 100 may further include an alignment device 130. The alignment device 130 is connected to the host computer 120 by signal and is detachably disposed on the optical fiber array 230. The host computer 120 controls the alignment device 130 (e.g., a robotic arm) to adjust the position of the optical fiber array 230 coupled to the photonic chip 220, thereby changing the second conversion efficiency received from the measuring device 110. When the second conversion efficiency approaches the first conversion efficiency, the optical fiber array 230 can be fixed on the photonic chip 220. Thus, the optoelectronic efficiency adaptation system 100 of the present disclosure can be applied to the optical millimeter wave antenna device 200, and integrates the line loss efficiency adjustment in the first loop and the optical coupling efficiency adjustment between the photonic chip 220 and the optical fiber array 230 in the second loop.

[0051] Please also read Figure 1 , Figure 2 and Figure 3 ,in Figure 2 is a flow chart illustrating a method 300 for adjusting photoelectric efficiency according to a second embodiment of the present disclosure. Figure 3 It is shown Figure 2 FIG. 3 is a comparison diagram of the first conversion efficiency C1 and the second conversion efficiency C2 in the photoelectric efficiency adaptation method 300. The photoelectric efficiency adaptation method 300 can be automatically executed via the photoelectric efficiency adaptation system 100, and includes the following steps S01, S02, and S03.

[0052] Step S01 is to control the measuring device 110 through the host computer 120 to provide the first input signal Sin_1 to the optical millimeter wave antenna device 200, and to make the first input signal Sin_1 pass through the first loop formed by the electronic chip 210 to generate the first output signal Sout_1, and then calculate and generate the first conversion efficiency C1 corresponding to the first loop according to the first input signal Sin_1 and the first output signal Sout_1. In step S01, the measuring device 110 can obtain the corresponding first input power (e.g., 10 dBm) when providing the first input signal Sin_1, and measure the first output signal Sout_1 received from the optical millimeter wave antenna device 200 to obtain the corresponding first output power (e.g., 9 dBm). Therefore, the measuring device 110 can calculate the first conversion efficiency C1 (i.e., 90%) and its corresponding power loss (i.e., 1 dBm) based on the first input power and the first output power.

[0053] In step S02, the host computer 120 controls the measuring device 110 to provide the second input signal Sin_2 to the optical millimeter wave antenna device 200, and the second input signal Sin_2 is passed through the second loop formed by the electronic chip 210, the photonic chip 220 and the optical fiber array 230 to generate the second output signal Sout_2, and then the second conversion efficiency C2 corresponding to the second loop is calculated based on the second input signal Sin_2 and the second output signal Sout_2. In step S02, the measuring device 110 can obtain the corresponding second input power (e.g., 10 dBm) when providing the second input signal Sin_2, and measure the second output signal Sout_2 received from the optical millimeter wave antenna device 200 to obtain the corresponding second output power (e.g., 7 dBm). Therefore, the measuring device 110 can calculate the second conversion efficiency C2 (i.e., 70%) and its corresponding power loss (i.e., 3 dBm) based on the second input power and the second output power.

[0054] Step S03 is to control the alignment device 130 through the host computer 120 to adjust the position of the optical fiber array 230 coupled to the photonic chip 220, thereby changing the second conversion efficiency C2. Figure 3As shown, after each adjustment of the coupling position, the host computer 120 reads the current second conversion efficiency C2 from the measuring device 110, and compares the second conversion efficiency C2 with the first conversion efficiency C1 using the first conversion efficiency C1 as a reference line. If the second conversion efficiency C2 is still far from the first conversion efficiency C1, the alignment device 130 is continuously controlled to adjust the position of the optical fiber array 230 until the second conversion efficiency C2 closest to the first conversion efficiency C1 is found. When the second conversion efficiency C2 approaches the first conversion efficiency C1 (i.e., the second conversion efficiency C2 is closest to the first conversion efficiency C1), the optical fiber array 230 is fixed to the photonic chip 220. For example, if the optical fiber array 230 is moved to a certain coupling position, the second conversion efficiency C2 can reach 85% at this time, and the corresponding power loss is 1.5dBm. Since the conversion efficiency of 85% is closest to the first conversion efficiency C1 of 90%, the optical fiber array 230 can be arranged at the aforementioned coupling position and fixed to the photonic chip 220 to optimize the overall photoelectric conversion efficiency of the optical millimeter-wave antenna device 200 .

[0055] Please also read Figures 1 to 4 and Figure 5 ,in Figure 4 It is shown Figure 2 Schematic diagram of the optical millimeter wave antenna device 200 used in the photoelectric efficiency adaptation method 300, Figure 5 It is shown Figure 4 Schematic diagram of the optical fiber array 230 of the optical millimeter wave antenna device 200. Figures 1 to 5 As shown, the optical millimeter wave antenna device 200 may further include an optoelectronic substrate 201, a switch 240, a processor 250, an antenna module 260 and a connector 270. The electronic chip 210, the photonic chip 220 and the switch 240 are all disposed on one side of the optoelectronic substrate 201. The switch 240 is electrically connected between the electronic chip 210 and the photonic chip 220, and may include a plurality of pins P1, P2, P3, and P4. The antenna module 260 may be, but is not limited to, a millimeter wave array antenna, and includes an antenna substrate 261 and an antenna 262. The antenna substrate 261 is disposed on the other side of the optoelectronic substrate 201, and the processor 250, the antenna 262 and the connector 270 are disposed on the antenna substrate 261. The processor 250 may be, but is not limited to, a microcontroller unit (MCU), and is coupled to the switch 240 via the antenna carrier 261 and the optoelectronic carrier 201, and is controlled by the host computer 120 to switch the switch 240 on and off. The processor 250 may also be used to adjust the phase difference of the driving signal sent by the electronic chip 210 to the antenna 262 to achieve beamforming.

[0056] In addition, the electronic chip 210 may include a transmitter 211 and a receiver 212. The transmitter 211 outputs a signal to the measuring device 110 via the antenna 262, and the receiver 212 receives an input signal from the measuring device 110 via the antenna 262. In some embodiments, the measuring device 110 may perform an Over-The-Air (OTA) measurement of the radiation pattern of the antenna 262 via a horn antenna (not shown separately), or utilize a probe station (not shown separately) coupled to the connector 270 (e.g., R5 port) to measure the output signal of the transmitter 211. The photonic chip 220 may include a light detector 221 and a light modulator 222. The light detector 221 is used to convert an optical signal from the optical fiber array 230 into an electrical signal, and the light modulator 222 is used to convert another electrical signal (i.e., input signal) from the receiver 212 into another optical signal.

[0057] In some embodiments, step S01 may include controlling the processor 250 to switch the switch 240 through the host computer 120, so that the switch 240 connects the receiver 212 to the transmitter 211 to form a first loop; and receiving the first output signal Sout_1 from the transmitter 211 through the measuring device 110, thereby calculating and generating a first conversion efficiency C1 according to the first input signal Sin_1 and the first output signal Sout_1. In step S01, the host computer 120 may control the processor 250 through an instruction, and the processor 250 short-circuits the pins P1 and P2 of the switch 240 through a control signal, disconnects the pins P1 and P4, and disconnects the pins P2 and P3, thereby electrically connecting the receiver 212 to the transmitter 211 to form a first loop.

[0058] In some embodiments, step S02 may include controlling the processor 250 through the host computer 120 to switch the switch 240 on and off, so that the switch 240 connects the receiver 212 to the optical modulator 222 and connects the optical detector 221 to the transmitter 211 to form a second loop; and receiving the second output signal Sout_2 from the transmitter 211 through the measuring device 110, thereby calculating and generating a second conversion efficiency C2 according to the second input signal Sin_2 and the second output signal Sout_2. In step S02, the host computer 120 controls the processor 250 through another instruction, and the processor 250 disconnects the pin P1 and the pin P2 of the switch 240 through another control signal, short-circuits the pin P1 and the pin P4, and short-circuits the pin P2 and the pin P3, thereby forming a second loop.

[0059] In some embodiments, the first loop may include a first line path LP1, and the first line path LP1 is formed between the antenna module 260 and the electronic chip 210. The second loop includes a first line path LP1 and a second line path LP2, and the second line path LP2 is formed between the electronic chip 210 and the photonic chip 220. Specifically, the first line path LP1 may be a line connected from the antenna 262 of the antenna module 260 to the electronic chip 210, and the path loss caused by this line is actually the power difference between the first input signal Sin_1 and the first output signal Sout_1. The second line path LP2 may be another line connected between the switch 240 coupled to the electronic chip 210 and the photonic chip 220. Compared with the first loop, the second loop has not only the path loss caused by the first line path LP1, but also the path loss caused by the second line path LP2 and the optical coupling loss between the photonic chip 220 and the optical fiber array 230. It can be seen that if the power loss corresponding to the first loop is 1 dBm and the power loss corresponding to the second loop is 3 dBm, the difference between the two power losses (2 dBm) is mainly contributed by the optical coupling loss.

[0060] like Figure 1 , Figure 4 and Figure 5 As shown, the photonic chip 220 may be provided with at least one optical waveguide 223. The optical fiber array 230 may be composed of a plurality of optical fibers 231 and an interposer 232, wherein the plurality of optical fibers 231 are disposed in the interposer 232 and are spaced apart from each other. In some embodiments, the diameter of the optical fiber 231 may be 10 millimeters (mm), and the diameter of the optical waveguide 223 may be 2 mm. Generally speaking, when laser light is incident from an optical fiber 231 with a larger diameter to an optical waveguide 223 with a smaller diameter, optical coupling loss will occur at the interface. Each optical fiber 231 may be, but not limited to, a single-mode optical fiber, and the interposer 232 may be, but not limited to, an ultraviolet (UV) adhesive film layer. The edge coupling between the optical fiber 231 and the optical waveguide 223 may be achieved by the interposer 232 in a compartment packaging manner, so that different forms of optical fiber sizes and shapes can be flexibly used.

[0061] In addition, step S03 may include controlling the alignment device 130 to move the intermediate layer 232 of the optical fiber array 230 through the host computer 120, thereby coupling one of the plurality of optical fibers 231 to the optical waveguide 223 of the photonic chip 220. When the host computer 120 determines that the second conversion efficiency C2 is close to the first conversion efficiency C1, optical clear adhesive (OCA) may be injected from an injection port 2321 of the intermediate layer 232, and ultraviolet rays may be irradiated to cure the optical adhesive, thereby fixing the optical fiber 231 to the optical waveguide 223. Thus, the optoelectronic efficiency adjustment method 300 disclosed in the present invention can be applied to the optical millimeter wave antenna device 200, and the switch 240 is used to switch the optoelectronic conversion path between the electronic chip 210 and the photonic chip 220, so as to achieve a mechanism for simultaneously verifying and adjusting the RF performance and the optical coupling. In addition, the compartment packaging method of the intermediate layer 232 can accurately and quickly align the optimal position of the optical coupling, thereby reducing the conversion loss of the spot size, thereby optimizing the overall optoelectronic conversion efficiency of the optical millimeter wave antenna device 200.

[0062] In summary, the optoelectronic efficiency adjustment method and optoelectronic efficiency adjustment system disclosed in the present disclosure have the following advantages: First, the optical coupling efficiency between the optical fiber array and the photonic chip and the line loss efficiency between the electronic chip and the antenna module can be integrated to optimize the optoelectronic efficiency. Second, the compartment packaging method using the intermediate layer can accurately and quickly align the optimal position of the optical coupling, and immediately adjust the optical fiber edge coupling efficiency, and at the same time confirm the adjustment mechanism of the line loss efficiency, thereby reducing the production test schedule and reducing the test cost.
