Abstract
We report a two-dimensional (2D) photonic crystal (PC) band-edge laser that was fabricated in an InGaAsP multiple-quantum-well structure by nanosphere lithography (NSL). NSL utilizes a nanosphere monolayer self-assembled into a hexagonal lattice as a mask for fabricating a 2D PC composed of circular air holes. A clear laser emission at around 1550 nm was observed under pulsed optical pumping. From the calculated band structure and polarization dependence measurement, the lasing is confirmed to occur at the M1-point band-edge mode. These results demonstrate that NSL, which does not require any sophisticated nanolithographic equipment, is a simple yet precise method for PC research and application.
