Abstract

A photonic crystal waveguide T-polarization beam splitter, comprising a photonic crystal waveguide with a completely forbidden band; after the input end (1) of the photonic crystal waveguide inputs an incident wave in any polarization direction into the polarization beam splitter, a TE component is outputted from a TE output end (2), and a TM component is outputted from the TM output end (3) of the beam splitter. The polarization beam splitter has a small size, high polarization and high light transmission efficiency, facilitates integration and has high efficiency, is suitable for large scale optical path integration, and achieves the functions of polarizing and beam splitting for different wavelengths.
