Silicon carbide photonic crystal optimized by artificial bee colony algorithm

The Artificial Bee Colony (ABC) algorithm was applied to solve an inverse design problem of integrated photonics. The ABC algorithm was applied to optimize large photonic bandgaps (PBGs) in 2D-dimensional PhCs composed of silicon carbide (SiC) and air, in a triangular lattice, for transverse magnetic polarization. The band diagram was calculated using the finite element method for the frequency domain. The ABC algorithm reached PhC structures with PBGs as large as 33.94%.
