Two-bit optical decoder based on micro-ring resonator

Abstract

The invention discloses a two-bit optical decoder based on a micro-ring resonator. The basic structure of the two-bit optical decoder is the micro-ring resonator, which is made by silicon-based nanowire waveguide. The optical decoder consists of two annular waveguides and three bent waveguides; two electric signals and a continuous optical signal with a working wavelength are input, and an optical signal is output. Supposing that: when a modulation voltage of a micro ring is a high level, the micro-ring resonator resonates, and when the modulation voltage of the micro ring is a low level, themicro-ring resonator does not resonate; an optical code of a two-bit electric signal can be obtained at the output end of the optical signal, so that the instrument finishes the function of the two-bit optical decoder. The two-bit optical decoder has the outstanding advantages that: by using the two-bit optical decoder, conversion from an electric signal to an optical signal can be realized, and the electric signal can be decoded optically at the same time. By using the ready-made process technology, the decoder has small volume, low power consumption, high speed and expansion and good application prospect in photon computers and optical communication networks, and is integrated with an electric element conveniently.

Description

technical field [0001] The invention relates to the technical field of optical decoders, in particular to a two-bit optical decoder based on a micro-ring resonator, which is particularly suitable for future photonic computers and optical communication networks. Background technique [0002] Existing computers transmit and process information electronically. With the advancement of semiconductor process technology, the size of transistors on a chip is getting smaller and smaller, and the number of transistors that can be integrated is increasing. In this way, the CPU can obtain a higher main frequency, but the most serious problem from the higher main frequency band is the sharp increase in power consumption, and the problems of leakage and heat dissipation cannot be solved. In terms of the development of high-speed computers, the use of electrons as information carriers can no longer meet people's requirements for faster processing speed of computers, and improving the comp...
