Description

technical field [0001] The invention relates to the technical field of preparation of microwave optoelectronic devices, in particular to a method and system for preparing dense wavelength division multiplexing devices with high precision. Background technique [0002] Microwave optical transmission, as one of the core transmission methods of signals such as local oscillators and clocks of modern radars and measurement and control systems, has large-scale and high-precision requirements for the phase delay between each sub-array. The application of dense wavelength division multiplexing technology can save circuit materials. For the circuit design of microwave optical transmission with such requirements, if no large-scale and high-precision production measures are taken, the production process will be extremely heavy, and the production accuracy cannot be guaranteed. Therefore, a high-precision preparation technology for dense wavelength division multiplexing device microwave...
