A series of nonlinear materials including GaAs, GaP, and ZnSe have been examined to determine their suitability for non-linear frequency conversion devices FCD and more specifically their use as high power, compact and broadly tunable IR and THz sources for applications in defense and security. The more mature GaAs was investigated to reveal the causes for the optical losses that restrict achievement of higher conversion efficiency in quasi phase matched FCD. The efforts to develop simple, cost effective techniques for fabrication of orientation patterned OP templates and to optimize the subsequent thick growth on these templates are presented.
