Paper Abstract

Birefringence, polarization, and wavelength filtering properties of subwavelength transmission gratings (SWTGs) and their applications in vertical cavity surface emitting lasers (VCSELs) are presented. Particularly, large birefringence (over two orders of magnitude larger than natural birefringence crystals) and polarization effects have been achieved in thin (240 nm thick or less) amorphous silicon subwavelength gratings (SWTGs). The SWTG polarizers were used to control the polarization of VCSELs (i.e., fixing, enhancing and switching of the polarization), making the maximum polarization of a VCSEL creased to 300:1 from 20:1. The SWTG's waveplates were used to build a polarization-switching VCSEL oscillator that has a can tunable frequency up to terahertz.
