Optical chip, photoelectric conversion apparatus, co-packaged optics chip, and optical communication device

A photoelectric conversion apparatus, comprising:

• at least one electronic integrated circuit (EIC);
• and
• an optical chip, comprising:
• an optical fiber connector comprising an optical fiber;
• a photonic integrated circuit (PIC);
• an injection molding layer;
• and
• a protective housing located between the injection molding layer and the PIC, wherein
• a coupling space is formed between the protective housing and the PIC;
• the optical fiber connector has a first connection end that faces the PIC and a second connection end that is away from the PIC and configured to detachably connect to another optical fiber connector;
• a first coupling end of the optical fiber passes through the first connection end;
• the first coupling end and a second coupling end of the PIC both extend into the coupling space;
• the first coupling end located in the coupling space is coupled to the second coupling end;
• and
• each of the at least one EIC is electrically connected to the optical chip.

An optical communication device, comprising:

• an outer housing;
• a circuit board;
• a driver;
• a laser;
• and
• a co-packaged optics chip comprising an photoelectric conversion apparatus, wherein
• an inside of the outer housing is configured to fasten the circuit board, and the driver, the laser, and the co-packaged optics chip are all packaged on a surface of the circuit board;
• and
• the driver is configured to drive the laser to send a first optical signal to the co-packaged optics chip, wherein the co-packaged optics chip is configured to modulate the first optical signal to obtain a modulated first optical signal, and the co-packaged optics chip is configured to emit the modulated first optical signal;
• or
• the co-packaged optics chip is configured to receive a second optical signal, and the co-packaged optics chip is further configured to convert the second optical signal into an electrical signal through optical-to-electrical conversion.
