Abstract
An optical reflective multiplexer chip, a laser transmitter chip, and an optical transmitter are disclosed. The optical transmitter includes the laser transmitter chip, an optical fiber, and the optical reflective multiplexer chip. The laser transmitter chip includes a bi-directional light emitting laser, a polarization splitter-rotator, and a first external port. The optical reflective multiplexer chip includes a combiner, a second external port, N third external ports, N microring resonant cavities, N polarization splitter-rotators, N first branch waveguides, and N second branch waveguides. The combiner is connected to the first branch waveguide, the second branch waveguide, and the second external port. The first external port is connected to the third external port by using the optical fiber.
