Abstract:

An overview of recent success in phase matching of second order nonlinear processes using Bragg reflection waveguides (BRWs) in compound semiconductors will be reported.  The technique utilizes dispersion properties of BRWs to achieve exact phase matching between the interacting frequencies.  Characterization of the fabricated devices for doubling mid-infrared light in pulse and continues wave regime will be presented.  Potential applications of the method in monolithically integrated optical parametric oscillators and integrated sources of photon-pairs will be highlighted.
