Principle of biconically fused fiber polarization beamsplitters(FPBS) has been introduced in this paper, and a new method for fabricating FPBS has been presented.

A polarization splitter based on ellipticai-hole rectangular-lattice two-core photonic crystal fibers is designed.

AOTF s requirements for polarization beamsplitter and its influence on AOTF s performances are discussed.

To Overcome the shortages of conventional polarizing beam splitters,narrow waveband and limited angle range,a polarizing beam splitter/combiner with wide waveband and angle range of 180° is developed.

A quantum key distribution system based on two polarization beam splitters;

We present the design and simulation of an ultra-compact high-efficiency polarization beam splitter(PBS) based on self-collimation effect and photonic crystal band gap in two dimensional photonic crystals.

Due to the splitter of the defect modes for s light and p light,this structure can be used as a polarization beam splitter.

The structure design and fabrication method of polarization beam splitters(PBS)with high extinction ratio and transmissivity have been introduced in this paper.

This paper introduced the distributed sensing principle of POTDR and the structure design of polarization beam splitters(PBS) with high extinction ratio and transmissivity.
