Description

Technical Field

[0001] The present invention relates to the technical field of multi-beam signal processing, and in particular to a multi-beam signal processing method based on an arrayed waveguide grating. Background Art

[0002] Traditional methods may rely on relatively simple optical components to control the pointing direction of the light beam. However, it is often difficult to accurately convert wavelength changes into spatial angle shifts through dispersion effects like arrayed waveguide gratings (AWGs), resulting in imprecise beam steering. Traditional methods may not be able to effectively solve the synchronization problem caused by delay differences during the propagation of multi-wavelength signals. However, delay compensation methods based on arrayed waveguide gratings and optical delay technology can ensure that the delay differences of multi-wavelength signals are accurately corrected, thereby achieving high-precision signal synchronization. Traditional methods generally have poor flexibility when processing multi-beam output arrays and cannot quickly adapt to changing signals or adjust beam shapes. Traditional beam adjustment methods usually rely on mechanical adjustments or complex optical components, resulting in an inability to quickly respond to changes during the dynamic reconstruction of multi-beam arrays. Traditional methods are often unable to compete with methods based on arrayed waveguide grating technology in terms of efficiency, accuracy, flexibility, and adaptability. The latter greatly improves the performance of multi-wavelength optical signal processing through precise beam control, delay compensation, and dynamic adjustment. Summary of the Invention

[0016] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the examples and accompanying drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0017] Example 1, as Figure 1 As shown, the present invention proposes a multi-beam signal processing method based on an arrayed waveguide grating, comprising: S1. Receive a target multi-wavelength optical signal based on an arrayed waveguide grating (AWG), and decompose the target multi-wavelength optical signal into different waveguide channels based on the wavelength diversity characteristic of the arrayed waveguide grating (AWG), so as to obtain an initial beam cluster corresponding to the target multi-wavelength optical signal; S2.

Dynamically reconstruct the multi-beam output array based on the phase tuning parameters and the parallel processing characteristics of the arrayed waveguide grating to obtain a multi-beam signal corresponding to the target multi-wavelength optical signal.

[0018] In the present invention, the arrayed waveguide grating is an optical device based on a waveguide array, which is usually used for wavelength selection and distribution. In the fields of optical signal processing, the arrayed waveguide grating realizes the decomposition, combination and transmission of light wave signals of different wavelengths through array waveguides and interference effects. Its key feature is that it can selectively distribute input light signals to different output channels according to wavelength; the wavelength diversity feature means that in the arrayed waveguide grating, light signals of different wavelengths will be distributed to different waveguide channels; the dispersion effect means that light signals of different wavelengths have different speeds during propagation, which causes the wavelength distribution of the signal to change. For the arrayed waveguide grating, the dispersion effect can convert the change in wavelength into a spatial angle shift, and light signals of different wavelengths present different angles at the output end of the arrayed waveguide grating; the primary beam array means that through the dispersion effect, light signals of different wavelengths in the initial beam cluster will have different angular shifts in space. After this process, the beam array obtained is called the primary beam array, which has certain directional characteristics; the phase distribution matrix refers to the phase distribution of each beam in space. In a multi-beam array, the phases of different beams are different. The difference determines their propagation direction and interference characteristics. The phase distribution matrix is a key parameter for designing and controlling beam direction. Optical delay technology achieves beam delay compensation by adjusting the propagation delay of optical signals. By adjusting the delay of different beams, the radiation pattern of the beam array can be optimized to ensure that the beams are emitted in the predetermined direction. A multi-beam output array is an array that can simultaneously output multiple independent beams. A phase tuner is used to adjust the phase of each beam in the array. By changing the phase of the beams, their propagation direction and interference characteristics can be controlled. The function of the phase tuner is to ensure that the directivity and beamwidth of multiple beams meet preset requirements. Phase gradient optimization control optimizes the directivity and width of the beam by adjusting the phase gradient (i.e., the phase difference between adjacent beams). Phase gradient optimization control makes the propagation of each beam more precise and meets the design requirements of the system. Dynamic reconstruction refers to the real-time adjustment and optimization of beam characteristics through the combined action of the arrayed waveguide grating and phase tuner. The direction, width, and intensity of the beam can be dynamically adjusted according to different application requirements, thereby achieving flexible processing of multi-wavelength optical signals.

[0019] This embodiment includes: decomposing a target multi-wavelength optical signal into different waveguide channels based on the wavelength diversity characteristics of an arrayed waveguide grating, including: A1. Based on the wavelength dependence of light, waveguide transmission interference is performed on the target multi-wavelength optical signal, and optical signals of different wavelengths are allocated to different waveguide channels; A2. The waveguide channel outputs an optical signal with a corresponding wavelength to obtain an initial beam cluster corresponding to the target multi-wavelength optical signal.

[0020] In this embodiment, waveguide transmission interference refers to the interference effect caused by different propagation speeds and refractive indices when optical signals of different wavelengths propagate in a waveguide. This interference effect can be used to distribute optical signals of different wavelengths to achieve wavelength diversity. A waveguide channel refers to the path through which optical signals are transmitted through a waveguide. In an arrayed waveguide grating, each waveguide channel transmits optical signals of different wavelengths, and each channel is responsible for outputting an optical signal of its corresponding wavelength.

[0021] In an optional embodiment, converting the wavelength variation of the beam corresponding to the initial beam cluster into a spatial angle offset includes: B1. Controlling the distance and length between beams corresponding to the initial beam cluster based on an arrayed waveguide grating (AWG) allows optical signals of different wavelengths to be offset at a specific angle when passing through the AWG, thereby obtaining a beam cluster with a specific angle offset. B2. Based on the preset directional characteristics, the distance and length between the beams corresponding to the beam group are adjusted again to obtain a primary beam array with the preset directional characteristics.

[0022] It should be noted that controlling the spacing and length between beams means designing the structure of the arrayed waveguide grating so that light signals of different wavelengths can be offset at a specific angle. This control ensures that the arrangement of the beams can meet the design requirements, usually to achieve a specific spatial distribution or enhance the directionality of the signal; the offset at a specific angle means that when light signals of different wavelengths pass through the arrayed waveguide grating, due to the geometric design and optical principles of the waveguide, they will undergo a certain angular offset in space. The angle of this offset is related to the different wavelengths and is usually precisely controlled through the design of the arrayed waveguide grating so that light signals of each wavelength can be emitted or received in a specific direction; the preset pointing characteristic refers to the directional characteristic of the light beam set in advance according to a specific application or design goal; the beam group refers to an optical wave group composed of multiple beams, which achieves spatial angular offset through the processing of the arrayed waveguide grating.

[0023] In an optional embodiment, the phase distribution matrix is used to determine the phase of each array element of the primary beam array to obtain the phase difference between the array elements corresponding to the primary beam array.

[0024] In an optional embodiment, accurately delay compensating the primary beam array based on the phase distribution matrix of the primary beam array and optical delay technology to obtain a multi-beam output array with a specified radiation pattern includes: C1. Obtaining the phase difference between array elements corresponding to the primary beam array based on the phase distribution matrix of the primary beam array; C2. Determine the specified radiation pattern of the multi-beam output array to ensure that the phase distribution of the array can support the transmission of multiple beams in different directions; C3. Performing time delay compensation on the primary beam array based on the specified radiation pattern and optical delay technology to adjust the phase difference between array elements corresponding to the primary beam array to obtain a multi-beam output array with the specified radiation pattern.

[0025] It should be noted that the phase difference between array elements refers to the deviation of the signal phase value relative to a reference element when each element in the array transmits or receives a signal. These phase differences are key factors in adjusting the direction and shape of the beam and are usually used to control the deflection, width and intensity of the beam. Delay compensation refers to adjusting the arrival time of the signal by applying different delays to each array element in a multi-beam array. This compensation can effectively adjust the phase difference of the array, thereby controlling the direction of the beam. Delay compensation is used to ensure that multiple beams can be emitted in a specified direction to meet specific radiation pattern requirements. A specified radiation pattern refers to a preset target radiation pattern, which describes the desired radiation direction and intensity distribution of the array in space. In a multi-beam array, a specified radiation pattern can be used to define the emission direction, intensity and coverage of each beam.

[0026] In an optional embodiment, determining a specified radiation pattern of a multi-beam output array includes: D1. Determine the target direction of the beam corresponding to the multi-beam output array; D2. adjusting the phases between the array elements corresponding to the multi-beam output array based on the target direction to obtain a multi-beam with the target direction; D3. Determine a specified radiation pattern based on the multi-beam to obtain a specified radiation pattern of the multi-beam output array.

[0027] In an optional embodiment, the phase tuner is used to adjust the phase difference of each unit of the multi-beam output array, thereby precisely controlling the direction and width of the beam.

[0028] In an optional embodiment, the phase gradient of the multi-beam output array is optimized and controlled based on a phase tuner to obtain phase tuning parameters that meet preset beam pointing and width requirements, including: E1. Adjusting the phase difference of the array elements corresponding to the multi-beam output array based on the phase tuner so that each beam corresponding to the multi-beam output array has maximum gain in the target direction to meet the preset beam pointing and width requirements; E2. Acquire phase tuning parameters of the phase tuner to obtain phase tuning parameters that meet preset beam pointing and width requirements.

[0029] It should be noted that the maximum gain in the target direction means that the energy concentration of the beam in this direction is maximized, so as to effectively cover the target area. In a multi-beam array, by adjusting the phase difference, each beam can have the maximum gain in the target direction, thereby improving the system performance; the beam pointing requirement means that the beam of the array needs to be accurately pointed to a specific target direction, and the beam width requirement refers to the expansion range of the beam, that is, the lateral width of the beam. By adjusting the phase difference, the beam pointing and width can be controlled to ensure that the beam meets specific design requirements; the phase tuning parameter refers to the key parameter for controlling the phase tuner, which determines the phase difference between array units.

[0030] In an optional embodiment, adjusting the phase difference of the array elements corresponding to the multi-beam output array includes: F1. Install a phase tuner on the array unit corresponding to the beam output array to adjust the phase of the array unit corresponding to the multi-beam output array to obtain an adjusted phase difference of the array unit corresponding to the multi-beam output array; F2. Adjust the direction and width of each beam corresponding to the multi-beam output array based on the phase difference to obtain a multi-beam output array with maximum gain in the target direction.

[0031] It should be noted that pointing refers to the direction of beam propagation in space. By adjusting the phase of the array unit, the beam can be pointed to the predetermined target direction; width refers to the spatial expansion of the beam, which is usually expressed as the half-power width of the beam. The smaller the beam width, the more concentrated the beam and the stronger the directionality. The width can be controlled by adjusting the phase and amplitude of the array unit; maximum gain refers to the maximum value of the signal power emitted by the array in the specified beam pointing direction. Gain is an important indicator of array performance, which indicates the ability of the array to concentrate energy. By adjusting the phase difference and beam width, the maximum gain in the specified direction can be achieved; target direction refers to the direction in which the beam is desired to point. In a multi-beam output array, each beam has a predetermined target direction. The task of the array is to ensure that each beam can achieve the best gain in its target direction; by adjusting the phase difference, the directivity and gain of the beam can be optimized, so that the array can generate multiple beams in multiple directions at the same time, and each beam achieves the maximum gain in its target direction.

[0032] In an optional embodiment, dynamically reconstructing the multi-beam output array based on the phase tuning parameter and the parallel processing characteristics of the arrayed waveguide grating to obtain a multi-beam signal corresponding to the target multi-wavelength optical signal includes: G1, based on the parallel processing characteristics of the arrayed waveguide grating, the beams of different wavelengths corresponding to the multi-beam output array are processed in parallel and distributed to different output channels; G2. Adjusting the phase tuner based on the phase tuning parameter to obtain a multi-beam signal corresponding to the multi-beam output array that meets preset requirements; G3. Monitor the output direction and intensity of each beam of the multi-beam signal. If any deviation occurs, adjust the phase tuner again to ensure that the multi-beam signal meets the preset requirements to obtain the multi-beam signal corresponding to the target multi-wavelength optical signal.

[0033] It should be noted that the parallel processing characteristic refers to the ability to process multiple signals simultaneously. In a multi-beam output array, multiple beams of different wavelengths can be processed in parallel through an arrayed waveguide grating and allocated to different output channels, thereby realizing the simultaneous processing of multi-wavelength signals; multi-beam signals refer to multiple beam signals generated by a multi-beam output array. These beam signals can point in different directions and transmit different wavelengths or information. Each beam signal can have different gains and directions; deviation refers to the difference between the actual output beam direction or intensity and the preset requirements. When the output direction or intensity of the beam deviates, the phase tuner needs to be adjusted to correct these errors to ensure that the requirements are met.

[0034] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. 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.
