Abstract

En 中文
In this paper we show that by suitably tailoring the dispersion characteristics of a Bragg reflection waveguide ( BRW) mode, it is possible to achieve efficient photon pair generation over a large pump bandwidth while maintaining narrow signal bandwidth. The structure proposed consists of a high index core BRW with a periodically poled GaN core and periodically stratified cladding made up of alternate layers of Al0.02Ga0.98N and Al0.45Ga0.55N. Such photon-pair generators should find applications in realizing compact and stable sources for quantum information processing. (c) 2008 Optical Society of America.
