Silicon-based WDM optical transceiver module

Abstract

The invention provides a silicon-based WDM optical transceiver module comprising a silicon photonic chip including a modulator array and a detector array; and a wavelength division multiplexer and a demultiplexer achieved based on a planar lightwave circuit (PLC). The wavelength division multiplexer and the modulator array are connected through packaging. The demultiplexer is connected to the detector array connected through packaging. A WDM optical module is achieved by packaging the wavelength division multiplexer chip and the demultiplexer chip through the silicon photonic chip and the PLC so as to avoid process difficulty of the silicon-based wavelength division multiplexer/demultiplexer. In view of low integration and high power consumption of a traditional WDM optical transceiver module based on discrete devices and PLC, the modulator array and the detector array are integrated by using silicon photon technology so as to greatly improve the integration of optical transceiver module and to reduce power consumption.

Description

technical field [0001] The invention belongs to the field of semiconductors and optoelectronic integration, in particular to a silicon-based WDM optical transceiver module realized by hybrid integration of silicon photonics and PLC. Background technique [0002] With the continuous improvement of people's requirements for information transmission and processing speed and the advent of the era of multi-core computing, metal-based electrical interconnections will become a development bottleneck due to defects such as overheating, delay, and electronic interference. The use of optical interconnection to replace electrical interconnection can effectively solve this problem. In the specific implementation of optical interconnection, silicon-based optical interconnection has become the first choice due to its unparalleled cost and technical advantages. Silicon-based optical interconnection can not only give full play to the advantages of fast optical interconnection speed, large ...
