Modified spontaneous emission from laterally injected photonic crystal emitter

The first use of lateral current injection to excite membrane photonic crystal light emitters is reported. The devices utilise a transverse diode that is created via ion implantation into a 280 nm-thick InGaAsP membrane. Photonic bandgap effects and spectral tuning of the electroluminescence spectra due to the graphene geometry photonic crystal are presented.
