Transverse and polarization mode controlled vertical cavity surface emitting laser with metal nano-aperture array for optical near-field applications

Abstract

This paper proposes and demonstrates the polarization and transverse mode controlled VCSEL with a metal nano-aperture array for efficient generation of optical near-field. The single-transverse mode operation with SMSR over 30 dB and tight polarization control is achieved at the same time. The proposed structure would be useful for polarization and transverse mode control in bottom emitting VCSELs.
