Enhanced Thermo-Optic Efficiency of Silicon Photonic Switch with Passively Aligned Nematic Liquid Crystals

Not Accessible

Your library or personal account may give you access

Abstract

We propose a new technique to achieve low power consumption in silicon thermo-optic switches without sacrificing speed. By incorporating subwavelength gratings and nematic liquid crystals, a switching power of 3.7 mW is achieved.
