Abstract

Official abstract text for this publication.

A photonic crystal waveguide TM-polarization 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 splitter, a TM wave is outputted from the output end ( 2 ) of the polarization splitter, and a TE wave is reflected back from the input end ( 1 ) of the polarization splitter. The TM-polarization 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.

First claim

Opening claim text (preview).

What is claimed is: 1. A TM-polarization splitter based on a photonic crystal waveguide, comprising a waveguide formed in a photonic crystal with a complete photonic bandgap, after the incident wave with any polarization direction is inputted into the polarization splitter via the input port of the photonic crystal waveguide, TM wave is outputted from the output port of the polarization splitter, while the TE wave is reflected from the input port of the polarization splitter, where…
