Abstract

The invention discloses a multifunctional optical generation device for millimeter waves, a Nyquist waveform and a triangular waveform, which solves the problems of the traditional millimeter wave signal source that millimeter wave generation can only be combined with the generation of one special waveform, so that the function integration level is low, the applicable range is narrow, and the millimeter wave generation and the generation of more than one special waveform cannot be integrated. The device has the advantages that the millimeter wave generation, Nyquist waveform generation and triangular waveform generation are combined, so that frequency-tripled millimeter wave signals, the Nyquist waveform and the triangular waveform can be generated under a same system structure through an optical method without filtering devices or changes to the system modulation depth, which achieves the integration of the millimeter wave generation and the generation of more than one special waveform, greatly improves the function integration level and operability of the millimeter wave signal source, further greatly widens the application range of the millimeter wave signal source, and is extremely beneficial to communication (especially optical communication), radars, sensing, etc.

Description

technical field [0001] The invention relates to a multifunctional millimeter wave, Nyquist waveform, and triangular waveform optical generating device, which is suitable for technical fields such as communication, radar, and sensing. Background technique [0002] The advent of the "5G" era has brought high-speed, high-capacity communications into the public eye. In order to meet people's growing demand for high-quality network multimedia, the traditional communication technology based on electronic methods is gradually being replaced by optical communication technology, and is developing in the direction of high frequency, high multiplexing, and high integration. [0003] At present, both Samsung and Nokia have announced the "5G" commercial standard that is being tested within the company. The communication frequencies used are all in the millimeter wave band, which means that millimeter wave will become the darling of the next generation communication technology, and it als...
