Abstract

A transmitter optical module for emitting a polarization polarized combined beam is disclosed. The transmitter optical module includes optical sources each emitting optical beams with substantially the same polarizations, an optical isolator, and a polarization beam combiner. The optical isolator, by receiving the optical beams, outputs the optical beams with polarizations perpendicular to each other to the polarization beam combiner.
