We report recent advances in electrically controlled photonic crystal nanocavity light sources and modulators, including an electrically pumped laser with 181nA threshold, an ultrafast single-mode LED with sub-fJ/bit operation energy, and modulator with 0.2 fJ/bit modulation energy. Additionally, we model the electrical and thermal performance of the lateral p-i-n geometry utilized in these devices, determining design criteria for efficient electrical injection and finding minimal self-heating.
