Abstract

We investigate the air-hole shape of photonic-crystal lasers in the vertical direction to increase the radiation constant for the surface emission. Numerical analysis indicates a maximum radiation constant when the air-hole depth is half the wavelength and a minimum when it is about the same as the wavelength, due to the interference of light waves diffracted in the vertical direction. We propose an air-hole design using two photonic-crystal layers offset by a half-period; the design more than doubles the radiation constant over that of a conventional design, leading to higher-power operation.
