Problems solved by technology

[0003] The conventional high-frequency simulation method is to analyze the linear behavior of the electro-absorption modulator and its package, but the electro-absorption modulator works under the condition of large signal excitation, which will inevitably produce nonlinear behavior. Therefore, by These conventional high-frequency simulation methods cannot accurately evaluate the high-frequency performance of the electro-absorption modulator and its packaging

Abstract

The invention discloses a simulation method, device, system and computer storage medium of an electro-absorption modulator. The method includes: fitting a small-signal equivalent circuit model of the electro-absorption modulator through preset simulation software; Bias current, testing the P-V characteristic curve of the electro-absorption modulator, and obtaining the nonlinear behavior function of the electro-absorption modulator according to the P-V characteristic curve; according to the small-signal equivalent circuit model and The nonlinear behavior function simulates the electro-absorption modulator to obtain simulation data corresponding to the electro-absorption modulator and its package. The present invention considers the non-linear behavior of the electro-absorption modulator when simulating the electro-absorption modulator, and can more accurately and comprehensively evaluate the high-frequency performance of the electro-absorption modulator and its packaging.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a simulation method, device, system and computer storage medium of an electroabsorption modulator. Background technique [0002] In recent years, with the development of high-speed long-distance communication technology, ElectroAbsorption Modulator (EAM, ElectroAbsorption Modulator) has also been widely used. However, at the same time as the packaging design of the electro-absorption modulator, strict high-frequency simulation of the electro-absorption modulator is required. [0003] The conventional high-frequency simulation method is to analyze the linear behavior of the electro-absorption modulator and its package, but the electro-absorption modulator works under the condition of large signal excitation, which will inevitably produce nonlinear behavior. Therefore, by These conventional high-frequency simulation methods cannot accurately evaluate the high-frequen...
