Optical packaging and design for optical transceivers

摘要

The optical transmitter is coupled to a transmitter support bench coupled to a printed circuit board, different semiconductor laser assemblies coupled to the transmitter support bench to emit laser beams of different laser wavelengths to deliver communication signals of different laser wavelengths, coupled to the transmitter support bench A wavelength multiplexing device positioned to receive a laser beam from a semiconductor laser assembly and combine different laser beams into the combined output laser beam as the output of the optical transceiver; And for reducing the unwanted optical feedback to the wavelength multiplexing device and the semiconductor laser assembly upon receiving the combined output laser beam, while preventing light from propagating in the opposite direction to the combined output laser beam. And a positioned optical isolator.
