A vertical-cavity surface-emitting laser with a two-dimensional photonic crystal (PC) structure was discussed for a single lateral mode operation. A seven-point defect structure was found to be proposed to enhance the confinement effect which was diluted by finite hole depth of the PC structure. A pure PC confined mode under room-temperature cw conditions with a PC lattice constant of 2 μm, hole diameters of 1.0 and 1.4 μm and depths of 1.85 and 1.92 μm respectively was also elaborated.
