Abstract :
In this article, we have discussed the influence of various thicknesses on different layers in AlGaInP-based Photonic Crystal Surface Emitting Lasers (PCSELs) by transfer matrix method to obtain the highest vertically optical confinement factor. Furthermore, we simulated the threshold gain of the optimized structure by coupled-wave theory. The important relation between the threshold gain and filling factor of photonic crystal has also been calculated.
