Micro-ring wavelength control method, system, device and storage medium

Abstract

The invention discloses a micro-ring wavelength control method, a system, a device and a computer readable storage medium. The method comprises the steps that a first monitoring signal of the input end of a micro-ring modulation circuit and a second monitoring signal of the output end of the micro-ring modulation circuit are obtained; performing first preset processing on the first monitoring signal to obtain a first electric signal; performing second preset processing on the second monitoring signal to obtain a second electric signal and a third electric signal; judging whether the micro-ring works in a preset state according to the first electric signal and the second electric signal to obtain a judgment result; under the condition that the judgment result shows that the micro-ring does not work in the preset state, determining a first control signal for adjusting the working wavelength of the micro-ring and a preset signal for realizing the working wavelength compensation of the micro-ring based on the first electric signal and the second electric signal; determining a second control signal for adjusting the working wavelength of the micro-ring according to the third electric signal and a preset signal; and controlling the resonant wavelength of the micro-ring based on the first control signal and the second control signal so as to compensate the drift of the working wavelength of the micro-ring.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of optical communication, and in particular to a method, system, device and storage medium for controlling the wavelength of a microring. Background technique [0002] The microring resonator-type modulator based on the silicon-based photonics integration platform has the characteristics of high integration, low power consumption, and compatibility with CMOS technology. It has very strong commercial value and is one of the focuses of industry research. At present, some international technology-advanced companies, such as Intel Corporation, have exhibited product samples based on silicon-based microring modulators, and are rapidly advancing towards actual products. However, due to the small operating wavelength range of the microring modulator, in practical applications, it is necessary to lock its operating wavelength in real time. Because the microring modulator is very sensitive ...

[0003] However, the common wavelength locking circuit needs to collect the monitoring signal for signal processing, and then feed back and control the wavelength adjustment element of the microring according to the signal processing result. The entire feedback control loop causes a large time delay, so that the microring wavelength control Less precise and less accurate
