Polymer Fiber Polarizer for Terahertz Applications

Polymer Fiber Polarizer for Terahertz Applications

An all-polymer fiber polarizer is proposed for terahertz applications. The polarizer is based on a mechanism which makes use of subwavelength fibers and absorption films. Several centimeters of the film could give an extinction ratio of 30 dB, while keeping the insertion loss below 4 dB. Experiments...

Zusammenfassung:An all-polymer fiber polarizer is proposed for terahertz applications. The polarizer is based on a mechanism which makes use of subwavelength fibers and absorption films. Several centimeters of the film could give an extinction ratio of 30 dB, while keeping the insertion loss below 4 dB. Experiments have been conducted to verify the mechanism and distinct polarization-dependent absorptions have been obtained.
