Abstract

An electrically pumped surface-emitting photonic crystal laser has a second surface of a first metal electrode arranged on a photonic crystal structure, a first electrical currents confining structure and a filled layer, and a substrate having a top surface arranged on a first surface of the first metal electrode for the photonic crystal structure to be inversely disposed. The photonic crystal laser has its epitaxy structure etched from above to fabricate the photonic crystal to allow laser beams to be reflected by the first metal electrode due to the inverse disposition and to be emitted from a rear surface of the epitaxy structure.
