Abstract :
The equifrequency surface plot is demonstrated as a powerful tool in obtaining the angular geometries that maintain quasi-phase matched (QPM) conditions for enhanced SHG with extended tuning range. These results are promising for the practical realisation of nonlinear frequency conversion devices based on GaN and related materials.
