Abstract

The invention relates to an optical waveguide technology, solving the problem that the traditional light transceiver is assembled by using discrete components massively and can not be produced in batch and providing a multi-channel light transceiver. The multi-channel light transceiver comprises a gain medium module, a detection medium module and a photon integrating chip, and is characterized inthat the photon integrating chip is fixedly connected with the gain medium module and the detection medium module. The invention has the advantages that since no discrete components and no movable components exist in the transceiver, by fully utilizing the traditional developed semiconductor processing process, the defect of low yield caused by deeply complicated chip growth processing required during the integration of a compound semiconductor uniwafer can be voided and the yield is improved. The invention is suitable for the light transceiver.

Description

technical field [0001] The invention relates to optical waveguide technology, in particular to an optical transceiver. Background technique [0002] Traditional optical transceivers are assembled with a large number of discrete components, resulting in high cost and complex mass production process. With the rapid development of planar optical waveguide manufacturing technology, optical passive devices based on photonic integrated chips are entering in large quantities. Commercial, such as optical splitter (Splitter), arrayed waveguide grating (AWG), etc., are becoming popular products in the optical communication market. Corresponding to this situation, in the field of optical active devices, due to the need to integrate III -V semiconductor material lasers (Laser Diode), detectors (Photo-Detector), etc. are integrated on a platform with some silicon dioxide or silicon material passive devices, which increases the complexity of the processing technology and the difficulty of...
