Description

technical field [0001] The present invention relates to the technical field of optical signal processing, and more particularly, to a thermo-optic phase modulation structure. Background technique [0002] With the popularity of optical communication and optical transmission, traditional micro-optical devices are being replaced by integrated optics and integrated optoelectronic devices. In the field of microwave technology, the signal bandwidth is increasing day by day. Limited by the electronic bandwidth bottleneck, it is very difficult to perform ultra-high broadband signal processing in the electrical domain, and the optical domain signal processing technology of microwave signals has received increasing attention and extensive research. [0003] Optical waveguide phase modulator is an important device in integrated optics. It is widely used in high-speed digital-to-analog conversion, optical logic circuit, optical sensing technology, etc. The modulation mechanism is main...
