Design of broadband reflector at the visible wavelengths using particle swarm optimization

We design and theoretically investigate freestanding gallium nitride (GaN) high contrast grating (HCG) membranes as broadband reflectors operating at the visible wavelengths. Optimization of the grating structural parameters is accomplished by using particle swarm optimization (PSO), and rigorous co...
