Abstract

We design a 10-fold photonic quasi-crystal fiber (PQF) for analyzing the efficiency of second harmonic generation (SHG). In this study we emphasize on lowering two factors, namely, overlap area and wave-vector mismatch which determine the efficiency of SHG. We find a trade off variation between these two factors with increment in pitch. Finally we optimize the relative efficiency of SHG as 84.87 %W -1 cm -2 for a 10-fold PQF, which is 35% higher than that of earlier reported relative efficiency of 6-fold PQF (62.96% W -1 cm -2 ).
