We propose to design a highly nonlinear SF6 soft 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 SF6 soft glass ES PCF modeling. The effect of tolerance on coherence length Lc and modal properties (effective index neff and overlap integral \(\gamma\) vs. 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 SF6 ES PCF modeling has been successfully analyzed.
