Abstract

The invention discloses a silicon-based optical random waveform generation chip. The chip comprises an optical frequency comb generation module, a filter module and an amplitude phase regulating arraymodule. The optical frequency comb generation module is composed of a tunable micro-ring resonator, the filter module is composed of cascading Mach-Zehnder interferometers, and the amplitude phase regulating array module is composed of a feedback array waveguide optical grating, a variable optical attenuator and a phase shifter. Any waveform generation inside the optical frequency region can be achieved, the chip has the advantages of being small in size, low in consumption, high in stability and the like, and the key role can be brought into play in an optical communication network and system.

Description

technical field [0001] The invention belongs to the field of optical communication, in particular to a silicon-based optical arbitrary waveform generating chip. Background technique [0002] With the rapid increase of services such as modern communication networks and computer networks, the amount of data is increasing explosively, and people have higher requirements for bandwidth. In order to meet the increasing demand for information capacity, the optical communication network will remain the core of the next generation network. Due to the continuous increase of optical communication capacity, the next-generation all-optical network has put forward higher requirements for active devices, especially light sources. Ultrashort pulse light source is one of the most dynamic research topics in the field of laser technology and high-speed optical communication applications, and has a huge application prospect. In practical applications, we not only need to generate high-quality...
