Abstract

the effects on the threshold pumping powers of membrane photonic crystal microcavity lasers, which originate from the spectral alignment between quantum-well optical gain and cavity resonance were investigated. An array of 31 suspended membrane PC microcavity lasers was fabricated in which the lattice constant varies in 2 mm increments between neighboring elements of the array. Removing 19 holes from a triangular lattice of air holes, which perforates a 224-nm-thick InGaAsP membrane on an InP substrate, forms each of these microcavity lasers.
