Analysis for second harmonic generation of SF_6 soft glass PCF using 2D-FDTD technique

摘要

AbstractWe propose to design a highly nonlinear SF6soft glass equiangular spiral (ES) PCF for investigating the mathematical analysis of second harmonic generation using 2D-FDTD technique. It reports that the second harmonic generation output power in silica PCF is prominently less compared to the highly nonlinear SF6soft glass ES PCF modeling. The effect of tolerance on coherence length Lcand modal properties (effective index neffand overlap integral$$gamma$$γvs. pitch ∧) of ES PCF is also shown. Furthermore, we have discussed the phase matching between fundamental and second harmonic mode using quasi phase matching technique. In addition, the ultralow bending loss in the SF6ES PCF modeling has been successfully analyzed.
