Abstract
An optical amplifier includes a plurality of photon amplifying regions. Each photon amplifying region includes a bottom electrode, an insulating layer formed over the bottom electrode, and having a through hole to the bottom electrode, a semiconductor layer and a top electrode formed over the semiconductor layer, wherein the top and bottom electrodes electrically contact the semiconductor layer. The semiconductor layer is formed over the insulating layer and in the through hole, and has a semiconductor active region in the through hole. The semiconductor active region has a direct electronic band gap with a conduction band edge, and is embedded within a photonic crystal having an electromagnetic band gap having photon energies overlapping the energy of the conduction band edge of the electronic band gap such that spontaneous emission of photons in the semiconductor active region is suppressed.
