Problems solved by technology
However, these two application modes use different optical transceivers, that is, they are independent applications. Therefore, when facing the evolution of communication transmission equipment towards miniaturization and generalization, if you want to use different optical transceivers to Making communication transmission equipment have two application modes, it is difficult in terms of volume reduction, manufacturing cost, etc. and does not meet market requirements, thus hindering the further popularization and expansion of related technical fields

The invention provides a photonic integrated circuit chip. The photonic integrated circuit chip comprises a plurality of connection ports, a plurality of polarized light beam splitting structures, an optical detection structure, an interleaver and a modulator. The connection port is used for receiving a plurality of first optical signals to the photonic integrated circuit chip. The polarized light beam splitting structure is used for splitting a first optical signal passing through the polarized light beam splitting structure into a first mode optical signal and a second mode optical signal. The optical detection structure comprises a first beam splitter and a second beam splitter. The interleaver is configured to transmit the first mode optical signal or the second mode optical signal to the second beam splitter. The modulator is configured to transmit a plurality of second optical signals having different wavelengths to the interleaver. Wherein the interleaver further transmits the second optical signal to different connection ports according to different wavelengths of the second optical signal.
Description
technical field [0001] Embodiments of the present invention relate to a photonic integrated circuit chip, in particular to a photonic integrated circuit chip that integrates a duplex (Duplex) architecture and a single-fiber bidirectional (BiDi) architecture into a single universal chip. Background technique [0002] In modern high-speed communication networks, such as nodes such as cloud centers and user terminals, optical transceivers (transceivers) are generally installed in electronic communication equipment. Through the application of optical fibers and optical transceivers, information transmission methods with high bandwidth, long distance, low loss, and no crosstalk interference can be realized. [0003] In the structure of a general optical transceiver, it can have an optical transmission module for electrical / optical signal conversion, which converts the data of the electrical signal type into a corresponding optical signal, and transmits the data through the optica...
