Fig. 1: The electrically biased sample structure, sample mounting scheme and a calculated temperature profile.

a A schematic of an electrically biased PC light-emission-device. Electrical current is injected directly to the metallic photonic crystal to excite localized surface plasmons. b A photo of the W-PC sample mounted to Ni contact wires and is supported by an Alumina ceramic mount. c A COMSOL computed temperature profile of the PC sample, Ni-contact pad and ceramic mount for PIN = 4 Watts. d A SEM image of the 3D tungsten PC and Si/SiO2 DBR (Distributed Bragg Reflector) micro-cavity structures.
