Abstract
An electrically pumped photonic-crystal surface-emitting lasers with optical detector comprises plurality of air holes, by the variation of position and size proportion form a photonic crystal having main structure and sub structure, and produces an optical detection signal by light guiding proportion of the light guiding tunnel, further have power proportion of the laser by reading the strength of the optical detection signal, so the automatic power control circuit can feedback the power proportion for controlling the surface-emitting laser.
