摘要:
Provided are a polarization beam splitter and an optical device with high productivity. A polarization beam splitter (PBS) according to an exemplary embodiment of the present invention includes: a demultiplexer (11) that is formed of a rib waveguide (50) and demultiplexes input light into first input light and second input light; a multiplexer (14) that is formed of the rib waveguide (50) and multiplexes the first input light and the second input light that are obtained by demultiplexing the input light by the demultiplexer (11); a first arm waveguide (12) that is formed of a channel waveguide (51) and guides the first input light to the multiplexer (11); and a second arm waveguide (13) that is formed of the channel waveguide (51), generates a phase difference in the first input light propagating through the first arm waveguide, and guides the second input light to the multiplexer (14).
