[0035] The solutions provided by the embodiments of the present disclosure will be described below in conjunction with exemplary embodiments.

[0036] Figure 1 Fig. 1 shows a structural schematic diagram of a light processing device according to an embodiment of the present disclosure; Figure 1 As shown in some exemplary embodiments, the light processing device provided by the embodiments of the present disclosure can include a light direction control component 110, a hollow core optical fiber 120, a light transceiver component 130, an optoelectronic conversion module 140, and a light signal generation component 150.

[0037] The light direction control component 110 is disposed on one side of the first end surface 121 of the hollow core optical fiber 120. The light direction control component 110 can change the direction of the light signal, and is configured to focus a light signal (hereinafter referred to as a first light signal) on the first end surface 121 of the hollow core optical fiber 120.

[0038] The first light signal can be exemplarily understood as a light signal transmitted in free space (such as air or vacuum), such as laser, infrared light, or quantum light, but is not limited to laser, infrared light, or quantum light.

[0039] The first end face 121 of the hollow core fiber 120 can be illustratively understood as an end face of the hollow core fiber 120 for receiving the optical signal in free space. The process of focusing the first optical signal onto the first end face 121 of the hollow core fiber 120 by the light direction control component 110 can be understood as the process of coupling the first optical signal to the hollow core fiber 120.

[0040] The optical transceiver component 130 is connected with the second end face 122 of the hollow core fiber 120, and is configured to receive the first optical signal from the second end face 122.

[0041] In some embodiments, the optical transceiver component 130 can be embodied as, but not limited to, a circulator. For example, in some examples, the optical transceiver component 130 can include a first beam splitter 131, a phase modulator 132, an attenuator 133, and a second beam splitter 134.

[0042] The first beam splitter 131 is connected with the second end face 122 of the hollow core fiber 120, and is configured to split the first optical signal from the second end face 122 into a first light beam and a second light beam.

[0043] The phase modulator 132 is connected with the first beam splitter 131, and is configured to perform phase modulation on the first light beam to obtain a third light beam.

[0044] The attenuator 133 is connected with the first beam splitter 131, and is configured to perform attenuation on the second light beam to obtain a fourth light beam.

[0045] The second beam splitter 134 is connected with the attenuator 133 and the phase modulator 132, and is configured to perform interference on the fourth light beam and the third light beam, and transmit the interference optical signal to the photoelectric conversion module 140 for processing.

[0046] The second beam splitter 134 is also connected with the optical signal generation component 150, and is configured to split the second optical signal from the optical signal generation component 150 into two signals, one of which is transmitted to the attenuator 133, and the other of which is transmitted to the phase modulator 132.

[0047] The first beam splitter 131 is also configured to combine the signals from the attenuator 133 and the phase modulator 132, and transmit the combined signal to the second end face 122 of the hollow core fiber 120.

[0048] For example, Figure 2 is a structural schematic diagram of an optical transceiver component in an embodiment of the present disclosure. As shown in Figure 2As shown, in some embodiments, the first beam splitter 131 can be exemplarily embodied as a Y-type optical fiber beam splitter. The second beam splitter 134 can be exemplarily embodied as an X-type optical fiber beam splitter. The attenuator 133 can be exemplarily embodied as an adjustable attenuator. The phase modulator 132 can be exemplarily embodied as any phase modulator. The c1 interface of the Y-type optical fiber beam splitter is connected with the second end face 122 of the hollow core optical fiber 120, the b1 interface is connected with the adjustable attenuator, and the a1 interface is connected with the phase modulator. The phase modulator is connected with the c2 interface of the X-type optical fiber beam splitter. The adjustable attenuator is connected with the d2 interface of the X-type optical fiber beam splitter. The a2 interface of the X-type optical fiber beam splitter is connected with the optical signal generation assembly 150. The b2 interface of the X-type optical fiber beam splitter is connected with the photoelectric conversion module 140.

[0049] The Y-type optical fiber beam splitter receives the first optical signal through the c1 interface and splits the first optical signal into a first light beam and a second light beam. The first light beam is transmitted to the phase modulator through the a1 interface. The phase modulator performs phase modulation processing on the first light beam to obtain a third light beam. The third light beam is transmitted to the X-type optical fiber beam splitter through the c2 interface.

[0050] The second light beam is transmitted to the adjustable attenuator through the b1 interface. The adjustable attenuator performs attenuation processing on the second light beam (for compensating the attenuation of the first light beam after passing through the phase modulator) to obtain a fourth light beam. The fourth light beam is transmitted to the X-type optical fiber beam splitter through the d2 interface.

[0051] The X-type optical fiber beam splitter performs interference processing on the third light beam and the fourth light beam, and sends the optical signal obtained by interference to the photoelectric conversion module 140 through the b2 interface for processing.

[0052] The X-type optical fiber beam splitter receives the second optical signal from the optical signal generation assembly 150 through the a2 interface, and splits the second optical signal into two optical signals. One optical signal is transmitted to the phase modulator through the c2 interface, and the other optical signal is transmitted to the adjustable attenuator through the d2 interface. After the two optical signals pass through the phase modulator and the adjustable attenuator, they are transmitted to the Y-type optical fiber beam splitter. The Y-type optical fiber beam splitter performs beam combining on the two optical signals, and transmits the combined signal to the second end face 122 of the hollow core optical fiber 120.

[0053] Through the above processing, the optical transceiver assembly provided by the embodiment can realize the integration of optical signal receiving and transmitting. Figure 2 The optical transceiver assembly provided by the embodiment can realize the integration of optical signal receiving and transmitting.

[0054] It should be noted that the optical transceiver assembly 130 in the present disclosure can be directly connected with the second end surface 122 of the hollow-core optical fiber 120, or can be indirectly connected with the second end surface 122 through other components. For example, in some examples, the optical transceiver assembly 130 can be connected with the second end surface 122 of the hollow-core optical fiber 120 through a single-mode optical fiber. One end of the single-mode optical fiber is fused with the second end surface 122, and the other end is connected with the optical transceiver assembly 130. Of course, this is only an example and is not the only way.

[0055] In some examples, the optical transceiver assembly 130 is connected with an optical amplifier 160, the optical amplifier 160 is connected with a filter 170, and the optical transducer module 140 is connected with the filter 170. Figure 1 In some examples, the optical transceiver assembly 130 is connected with an optical amplifier 160, the optical amplifier 160 is connected with a filter 170, and the optical transducer module 140 is connected with the filter 170.

[0056] In some examples, the optical transceiver assembly 130 is connected with an optical amplifier 160, the optical amplifier 160 is connected with a filter 170, and the optical transducer module 140 is connected with the filter 170.

[0057] For example, the optical transducer module 140 can be a single-photon detector, but is not limited to a single-photon detector. Figure 3 A schematic diagram of one connection mode of the optical transducer module and the optical transceiver assembly is shown. As shown in FIG. 1, in some example embodiments, the optical transceiver assembly 130 is connected with an optical amplifier 160, the optical amplifier 160 is connected with a filter 170, and the optical transducer module 140 is connected with the filter 170. Figure 3 The optical amplifier 160 is used to amplify the first optical signal from the optical transceiver assembly 130. The optical amplifier 160 can be an EDFA (Erbium-Doped Fiber Amplifier), but is not limited to an EDFA.

[0058] The filter 170 is used to filter the first optical signal from the optical amplifier 160. The filter 170 can be a narrow-band filter, but is not limited to a narrow-band filter.

[0059] The optical transducer module 140 is used to convert the optical signal from the filter 170 into an electrical signal.

[0060] By amplifying the first optical signal from the optical transceiver assembly 130 through the optical amplifier 160, the attenuation of the first optical signal can be reduced, and the transmission quality and transmission distance of the first optical signal can be improved. By filtering the first optical signal from the optical amplifier through the filter 170, interference signals can be filtered out.

[0061]

Figure 4 Figure 4 ​As shown, in some exemplary embodiments, the optical transceiver assembly 130 is connected to the filter 180, the filter 180 is connected to the decoding device 190, and the photoelectric conversion module 140 is connected to the decoding device 190.

[0063] The filter 180 is used to filter the first optical signal from the optical transceiver assembly 130. The filter 180 can be, for example, a narrowband filter, but is not limited to a narrowband filter.

[0064] The decoding device 190 is used to decode the optical signal from the filter 180.

[0065] The photoelectric conversion module 140 is used to convert the decoded optical signal into an electrical signal.

[0066] exist Figure 1 In this configuration, the optical signal generation component 150 is connected to the optical transceiver component 130. The optical signal generation component 150 generates a second optical signal and sends it to the optical transceiver component 130. The optical transceiver component 130 transmits the second optical signal from the optical signal generation component 150 to the second end face 122 of the hollow optical fiber 120. The optical direction control component 110 receives the second optical signal from the first end face 121 of the hollow optical fiber 120 and transmits it into free space for transmission.

[0067] Figure 5 A schematic diagram of one structure of an optical signal generation component provided in an embodiment of this disclosure is shown. For example... Figure 5 As shown, in some exemplary embodiments, the optical signal generation component 150 referred to in this disclosure may include: a light source 151 and an optical amplifier 152.

[0068] In this configuration, light source 151 is connected to amplifier 152. Amplifier 152 is connected to optical transceiver assembly 130. Light source 151 generates an optical signal and sends it to amplifier 152. Amplifier 152 amplifies the optical signal from light source 151 to obtain a second optical signal. Optical transceiver assembly 130 receives the second optical signal from amplifier 150. Light source 151 can be, for example, a laser source or an infrared source. The second optical signal can be, for example, laser light or infrared light. Amplifier 152 can be, for example, an EDFA, but is not limited to an EDFA.

[0069] Figure 6 A schematic diagram of another structure of the optical signal generation component provided in an embodiment of this disclosure is shown. For example... Figure 6 As shown, in some exemplary embodiments, the optical signal generation component 150 referred to in this disclosure may include: a light source 153, a filter 154, and an encoding device 155.

[0070] The light source 153 is connected with the filter 154. The light source 153 is configured to generate a light signal, such as quantum light. The filter 154, such as a narrowband filter, is configured to filter the light signal generated by the light source 153 to obtain a light signal of a specified wavelength. The encoding device 155 is connected with the filter 154 and configured to encode the light signal from the filter 154 to obtain a second light signal. The optical transceiver assembly 130 is connected with the encoding device 155 and configured to receive the second light signal from the encoding device 155.

[0071] In the embodiment of the present disclosure, the first light signal is focused on the first end face of the hollow core fiber through the light direction control assembly, the first light signal is received from the second end face of the hollow core fiber through the optical transceiver assembly, and the first light signal is sent to the optoelectronic conversion module for optoelectronic conversion, thereby realizing the reception of the light signal.

The embodiment of the present disclosure realizes the integration of the light signal transmission and reception, and improves the integration of the optical processing device. In addition, the hollow core fiber has the characteristics of large mode field diameter, low mode dispersion, low nonlinear effect, etc. The introduction of the hollow core fiber is beneficial to improve the tolerance to light spot drift, reduce the dependence on high-precision collimation and complex adaptive optical path, improve the fiber coupling efficiency, and improve the stability and reliability of the light signal reception. Moreover, the embodiment of the present disclosure does not need additional photonic lantern or mode multiplexing or demultiplexing device, which can effectively reduce the complexity and cost of the optical processing device.

[0072] In addition, the hollow core fiber can carry higher power light signals compared to single-mode fibers due to its low nonlinearity, low loss, and large mode field diameter, which meets the demand of large-capacity, high-power free-space laser communication. This is of great significance for long-distance, large-bandwidth, and high-power transmission.

[0073] In some embodiments, the hollow core fiber can be flexibly fused to a single-mode fiber to access the optical transceiver assembly or an optical amplifier such as an EDFA, thereby improving the flexibility of the structure of the optical processing device and facilitating deployment in different free-space optical communication and detection systems.

[0075] In some embodiments, the light processing device provided by the embodiments of the present disclosure can also be used for tasks such as laser radar, deep space exploration, target recognition, satellite high-speed communication, and the like, and the high coupling efficiency of the light processing device is conducive to improving the task capability.

[0076] Figure 7 A schematic diagram of the structural relationship between a light direction control assembly and a hollow optical fiber provided by the embodiments of the present disclosure is shown. As shown in Figure 7 In some exemplary embodiments, the light direction control assembly 110 can include a first lens 111. The first lens 111 can be, for example, a thin lens satisfying the diffraction limit. Plane P is the plane on which the first lens 111 is located, that is, the entrance pupil plane. Plane F is the focal plane of the first lens 111. The first lens 111 is used to converge the first light signal. The first end surface 121 of the hollow optical fiber 120 is used to receive the first light signal after the convergence processing.

[0077] Referring to Figure 7 In the case where no other components or parts are included between the first lens 111 and the first end surface 121, plane F can be coplanar with the first end surface 121 of the hollow optical fiber 120, and the focal point of the first lens 111 can be configured to fall on the first end surface 121.

[0078] According to Figure 7 In the embodiments of the embodiments of the present disclosure, in the case where no other components or parts are included between the first lens 111 and the first end surface 121, by configuring the focal plane of the first lens 111 to be coplanar with the first end surface 121 of the hollow optical fiber 120 and configuring the focal point of the first lens 111 to fall on the first end surface 121, the coupling efficiency of the hollow optical fiber can be improved.

As shown in Figure 8 In some exemplary embodiments, the light direction control assembly 110 can include a first lens 111, a second lens 112, a light reflection assembly 113, and a third lens 114.

[0080] The first lens 111 is used to converge the first light signal onto the second lens 112.

[0081] The second lens 112 is arranged between the first lens 111 and the light reflection assembly 113, and is used to perform beam combining processing on the first light signal from the first lens 111, so that the first light signal propagates to the light reflection assembly 113.

[0083] The third lens 114 is arranged between the light reflection component 113 and the first end surface 121 of the hollow optical fiber 120, and is configured to focus the first light signal reflected by the light reflection component 113 to the first end surface.

[0084] According to Figure 8 In the case where the first lens cannot directly converge the first light signal to the first end surface of the hollow optical fiber due to the layout position, the first light signal converged by the first lens can be combined by the second lens, the combined first light signal can be reflected by the light reflection component to the third lens, and the first light signal can be focused to the first end surface of the hollow optical fiber by the third lens, thereby improving the flexibility of the layout of the light processing device.

As Figure 9 shown, in some examples, the light direction control component 110 can include a first lens 111, a second lens 112, a light reflection component 113, and a third lens 114, and a filter 115.

[0086] The first lens 111 is configured to converge the first light signal to the second lens 112.

[0087] The second lens 112 is configured to combine the first light signal from the first lens 111, so that the first light signal propagates to the light reflection component 113.

[0088] The light reflection component 113 is configured to reflect the combined first light signal of the second lens to the third lens 114.

The filter 115 may, for example, be a narrowband filter, but is not limited to a narrowband filter.

[0090] The third lens 114 is configured to focus the filtered first light signal of the filter 115 to the first end surface 121.

[0091] According to Figure 9 In the example, by arranging the filter between the light reflection component and the third lens, the first light signal can be filtered before reaching the hollow optical fiber, and the interference signal can be removed.
