Description

Technical Field

[0001] This invention relates to the field of multi-beam signal processing technology, and more specifically to a multi-beam signal processing method based on an arrayed waveguide grating. Background Technology

[0002] Traditional methods may rely on relatively simple optical components to control the beam direction, and are often unable to accurately convert wavelength changes into spatial angular offsets through dispersion effects, as arrayed waveguide gratings do, resulting in imprecise beam control. Traditional methods may also fail to effectively solve synchronization problems caused by time delay differences in multi-wavelength signals during propagation. In contrast, time delay compensation methods based on arrayed waveguide gratings and optical delay technology can ensure that time delay differences in multi-wavelength signals are accurately corrected, thus achieving high-precision signal synchronization. Traditional methods generally lack flexibility when processing multi-beam output arrays, unable to quickly adapt to changing signals or adjust beam shapes. Traditional beam adjustment methods typically 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. In terms of efficiency, accuracy, flexibility, and adaptability, traditional methods often cannot compare with methods based on arrayed waveguide grating technology, which significantly improves the performance of multi-wavelength optical signal processing through precise beam control, time delay compensation, and dynamic adjustment.

The illustrative embodiments and descriptions of this invention are for illustrative purposes only and are not intended to limit the invention. It should be noted that this invention is already in the actual research and development stage.

[0017] Example 1, such as Figure 1 As shown, the present invention proposes a multi-beam signal processing method based on an arrayed waveguide grating, comprising: S1.

[0018] In this invention, an arrayed waveguide grating (AWR) is an optical device based on a waveguide array, typically used for wavelength selection and allocation. In fields such as optical signal processing, AWRs achieve the decomposition, combination, and transmission of optical signals of different wavelengths through arrayed waveguides and interference effects. Its key characteristic is its ability to selectively allocate input optical signals to different output channels based on wavelength. Wavelength diversity refers to the fact that in an AWR, optical signals of different wavelengths are allocated to different waveguide channels. Dispersion refers to the fact that optical signals of different wavelengths travel at different speeds during propagation, resulting in changes in the wavelength distribution of the signal. For AWRs, the dispersion effect can convert wavelength changes into spatial angular offsets, causing optical signals of different wavelengths to exhibit different angles at the output of the AWR. A primary beam array refers to the initial beam cluster where optical signals of different wavelengths are spatially offset by different angles due to the dispersion effect. The resulting beam array is called a primary beam array, and they possess 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... The phase 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 refers to adjusting the propagation delay of the optical signal to achieve beam delay compensation. By adjusting the delay of different beams, the radiation pattern of the beam array can be optimized to ensure that the beam is emitted in a predetermined direction. A multi-beam output array is an array that can output multiple independent beams simultaneously. A phase tuner is used to adjust the phase of each beam in the array. By changing the phase of the beam, their propagation direction and interference characteristics can be controlled. The role of the phase tuner is to ensure that the directivity and beamwidth of multiple beams meet the preset requirements. Phase gradient optimization control refers to optimizing the directionality 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 accurate and can meet the design requirements of the system. Dynamic reconfiguration refers to adjusting and optimizing the characteristics of the beam in real time under the combined action of the arrayed waveguide grating and the phase tuner. According to different application requirements, the direction, width, and intensity of the beam are dynamically adjusted to achieve flexible processing of multi-wavelength optical signals.

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

[0020] In this embodiment, waveguide transmission interference refers to the interference effect that occurs when light signals of different wavelengths propagate in a waveguide due to their different propagation speeds and refractive indices. The interference effect can be used to distribute light signals of different wavelengths to achieve wavelength diversity. A waveguide channel refers to the path through which light signals are transmitted. In an array of waveguide gratings, each waveguide channel transmits light signals of different wavelengths, and each channel is responsible for outputting the light 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. Based on the arrayed waveguide grating, the distance and length between the beams corresponding to the initial beam cluster are controlled so that optical signals of different wavelengths can be deflected at a specific angle when passing through the arrayed waveguide grating, so as to obtain a beam cluster with a specific angle deflection. B2. Based on the preset pointing characteristics, the distance and length between the beams corresponding to the beam group are adjusted again to obtain a primary beam array with preset pointing characteristics.

[0022] It should be noted that controlling the spacing and length between beams refers to designing the structure of the arrayed waveguide grating so that optical signals of different wavelengths can be offset at a specific angle. This control ensures that the beam arrangement meets design requirements, usually to achieve a specific spatial distribution or enhance the directionality of the signal. A specific angle offset means that when optical 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. This offset angle is related to the wavelength and is usually precisely controlled through the design of the arrayed waveguide grating, so that each wavelength of optical signal can be emitted or received in a specific direction. Preset pointing characteristics refer to the pre-set optical beam direction characteristics according to specific applications or design goals. A beam group refers to an optical group composed of multiple beams, which achieve 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, precise time delay compensation is performed on the primary beam array based on the phase distribution matrix and optical delay techniques to obtain a multi-beam output array with a specified radiation pattern, including: C1. Obtain the phase difference between the 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. Based on the specified radiation pattern and optical delay technology, time delay compensation is performed on the primary beam array to adjust the phase difference between the array elements corresponding to the primary beam array, so as to obtain a multi-beam output array with a specified radiation pattern.

[0025] It should be noted that the phase difference between array elements refers to the deviation of the signal phase value of each element in the array from a reference element when transmitting or receiving signals. These phase differences are key factors in adjusting the beam direction and shape, and are typically used to control the beam deflection, width, and intensity. Time delay compensation refers to adjusting the signal arrival time in a multi-beam array by applying different time delays to each array element. This compensation can effectively adjust the phase difference of the array, thereby controlling the beam direction. Time delay compensation is used to ensure that multiple beams can be transmitted in a specified direction to meet specific radiation pattern requirements. A specified radiation pattern refers to a preset target radiation mode, 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 transmission direction, intensity, and coverage of each beam.

[0026] In one optional embodiment, determining a specified radiation pattern of the multi-beam output array includes: D1. Determine the target direction of the beam corresponding to the multi-beam output array; D2. Adjust the phase 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 the specified radiation pattern based on the multi-beam array to obtain the specified radiation pattern of the multi-beam output array.

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

[0028] In an optional embodiment, phase gradient optimization control of the multi-beam output array is performed based on a phase tuner to obtain phase tuning parameters that meet preset beam pointing and width requirements, including: E1. The phase difference of the array units corresponding to the multi-beam output array is adjusted based on the phase tuner so that each beam corresponding to the multi-beam output array has the maximum gain in the target direction, so as to meet the preset beam pointing and width requirements. E2. Obtain the phase tuning parameters of the phase tuner to obtain phase tuning parameters that meet the preset beam pointing and width requirements.

[0029] It should be noted that the maximum gain in the target direction refers to the maximum energy concentration of the beam in that direction, 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 system performance. Beam pointing requirement refers to the requirement that the array beams need to be precisely pointed in a specific target direction, while beamwidth requirement refers to the beam's extension range, i.e., 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. Phase tuning parameters are the key parameters that control the phase tuner, and they determine the phase difference between array elements.

[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 in the array unit corresponding to the beam output array to adjust the phase of the array unit corresponding to the multi-beam output array in order to obtain the phase difference of the array unit corresponding to the multi-beam output array after adjustment. F2. Adjust the pointing and width of each beam in 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 "direction" refers to the direction of beam propagation in space. By adjusting the phase of the array elements, the beam can be directed towards a predetermined target direction. "Bandwidth" refers to the spatial extent of the beam, usually representing the half-power width of the beam. The smaller the beamwidth, the more concentrated and directional the beam. The width can be controlled by adjusting the phase and amplitude of the array elements. "Maximum gain" refers to the maximum signal power transmitted by the array in a specified beam direction. Gain is an important indicator of array performance, representing the array's ability to concentrate energy. By adjusting the phase difference and beamwidth, the maximum gain in a specified direction can be achieved. "Target direction" refers to the desired direction of the beam. In a multi-beam output array, each beam has a predetermined target direction. The array's task is to ensure that each beam achieves optimal gain in its target direction. By adjusting the phase difference, the directivity and gain of the beam can be optimized, allowing the array to generate multiple beams simultaneously in multiple directions, with each beam achieving maximum gain in its target direction.

[0032] In an optional embodiment, the multi-beam output array is dynamically reconstructed based on the phase tuning parameters and the parallel processing characteristics of the arrayed waveguide grating to obtain the multi-beam signal corresponding to the target multi-wavelength optical signal, including: G1. Based on the parallel processing characteristics of arrayed waveguide gratings, the beams of different wavelengths corresponding to the multi-beam output array are processed in parallel and allocated to different output channels. G2. Adjust the phase tuner based on the phase tuning parameters to obtain the multi-beam signal corresponding to the multi-beam output array that meets the preset requirements; G3. Monitor the output direction and intensity of each beam of the multi-beam signal. If a deviation occurs, readjust the phase tuner to ensure that the multi-beam signal meets the preset requirements in order to obtain the multi-beam signal corresponding to the target multi-wavelength optical signal.

[0033] It should be noted that parallel processing capability 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 assigned to different output channels, thereby achieving simultaneous processing of multi-wavelength signals. Multi-beam signals refer to multiple beam signals generated by the multi-beam output array. These beam signals can point in different directions, transmit different wavelengths or information, and each beam signal can have different gain and directionality. Deviation refers to the difference between the actual output beam direction or intensity and the preset requirements. When the output beam direction or intensity deviates, the phase tuner needs to be adjusted to correct these errors and ensure that the requirements are met.

[0034] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment 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 within the scope of protection of the present invention.
