Electro-optical 8-3 encoder

Abstract

The invention discloses an electro-optic 8-3 encoder comprising a first waveguide (110), a second waveguide (120), a third waveguide (130), a fourth waveguide (140), a first annular waveguide (101), a second annular waveguide (102), a third annular waveguide (103), a fourth annular waveguide (104), a fifth annular waveguide (105), a sixth annular waveguide (106) and a seventh annular waveguide (107), the annular waveguides are coupled with corresponding waveguides to form micro ring resonators, and an optical signal with a specific wavelength is output from an optical output end when one micro ring resonator in the micro ring resonators is in a resonant state. According to the electro-optic 8-3 encoder disclosed by the embodiment of the invention, the resonant states of the micro ring resonators can be controlled by electrical signals to control the output of the optical signal with the specific wavelength so as to realize an electro-optic encoding function.

Description

technical field [0001] The invention relates to the field of information processing, in particular to an electro-optic 8-3 encoder. Background technique [0002] With the reduction of the chip feature size, the increase of the number of transistors and the increase of the clock frequency, the leakage current of electronic devices gradually increases, and the interconnection wiring becomes longer and longer, resulting in an increase in the power consumption density of the chip, and excessive heat consumption Dispersion will degrade the performance of the chip. It is difficult for the development of integrated circuits to continue along Moore's Law, and electronic information processing has encountered a physical bottleneck. However, with the improvement of people's living standards, people put forward higher requirements for information processing, such as higher speed and higher performance requirements for information processing in video broadcasting, video telephony, and ...
