Abstract

The invention provides a broadband optical multi-beam integrated chip with flexible and controllable beam number and a method. The chip comprises N input channels, wherein each channel contains M optical signals with different wavelengths; N independent processing units, wherein each input channel corresponds to one independent processing unit, and each independent processing unit comprises a first-stage wavelength division demultiplexing module, M delay line modules and a wavelength division multiplexing module; a comprehensive processing unit connected with all the independent processing units and comprising an optical combiner and a second-stage wavelength division demultiplexing module. And the selection of the beam number and the beam pointing angle can be realized by selecting the input wavelength. According to the invention, the problem of flexible regulation and control of beam pointing and beam number is solved.

Description

technical field [0001] The invention relates to radar electronic warfare technology, in particular to a broadband optical multi-beam integrated chip with flexible and controllable beam number. Background technique [0002] In recent years, with the continuous development of military high technology, the electromagnetic environment of the modern battlefield has become more and more complex, which is manifested in the increasing signal density, wider frequency coverage and more complex signal patterns. This brings great challenges to the signal reconnaissance of electronic countermeasure equipment. Electronic countermeasure equipment needs to have wide airspace coverage, wide frequency range and near real-time high-sensitivity signal processing. Microwave photonics technology has natural advantages in solving the above problems. Microwave photonics technology gives full play to the technical characteristics of light in terms of broadband, high speed, parallelism and compactnes...
