Metal-clad photonic crystal membrane nanolasers

We report laterally injected photonic crystal membrane light emitters that are clad on one surface by metal. Light emission from an electrically injected photonic crystal defect cavity is reported. Carriers are injected via a lateral diode that is formed in an InGaAsP membrane using ion implantation. The membrane is removed from its native InP substrate and placed on a thin dielectric layer above Au. The Au-coated substrate provides a large index contrast and good thermal conduction. A cavity resonance in the DC electroluminescence and photopumped laser operation are both observed at room temperature.
