Recent progress in device physics and nanotechnology will enable a new generation of high performance laser diodes. This presentation will discuss the application of nanotechnology to achieve unprecedented confinement of both photons and electrons to develop the next generation of lasers, photonic integrated circuits, and sensors. The application of 2-dimensional photonic crystals into vertical cavity lasers to form coherent arrays and micro-fluidic sensors will be reported. Coherent coupling in arrays allows for increased power in the emission far field, which may be used in applications such as imaging, free space interconnects, and beam steering. The first gain localized electrically injected photonic crystal light emitters are explored with the goal of understanding their emission characteristics from theoretical and experimental perspectives.
