Abstract

The invention discloses a silicon photonics integration multi-wavelength optical sending and receiving module relating to the integration photonics structure field of the optical fiber communication field. The sending and receiving module comprises an optical sending unit and an optical receiving unit; when the optical sending unit carries out sending, the laser sent by a laser is filtered into multi-wavelength optical waves with equal wavelength intervals by silicon-based micro-ring filters; the multi-wavelength optical waves are respectively filtered by every silicon-based micro-ring modulator so as to obtain needed wavelengths; the optical waves with the wavelengths are loaded and modulated into optical signals; the optical signals are output to a silicon-based array waveguide grating; the silicon-based array waveguide grating combines the optical signals output by the silicon-based micro-ring filters; the combined optical waves are coupled to an optical fiber through silicone waveguide. According to the invention, the quantity of the sent optical waves can be increased; the wavelength intervals of the optical waves can be controlled; the integration degree is relatively high; the cost is relatively low; and the module of the invention can satisfy the need of a user and is applicable to popularization.

Description

technical field [0001] The invention relates to the field of integrated optical structures in the field of optical fiber communication, in particular to a silicon photon integrated multi-wavelength optical transceiver module. Background technique [0002] With the popularization of green and environmental protection, the optical communication industry has gradually developed towards the direction of high integration and low power consumption. Integrated small size, low power consumption, and low-cost optical communication transceiver modules are currently a hot spot in the market. In dense wavelength division or frequency division multiplexing systems, it is usually necessary to arrange multiple lasers and power supplies in the transmitter.
