A Plasmonic Laser Source Based On Bragg Reflection Waveguide

Abstract

We designed a new type of plasmonic laser source based on the Bragg reflection waveguide． This laser source is simple in structure and convenient for integration． It works under room temperature electrical pumping condition and outputs plasmonic laser with more than milliwatt power which is much larger than those demonstrated plasmonic laser sources with power of nano-watt scale． The proposed laser works at 808 nm． The tilted light beam offered by Bragg reflection waveguide directly couples into surface plasmon polaritons in our quasi-Otto configuration．
