Abstract:
Nanoscale light sources have great potential applications in high density data storage, single molecule detection, direct RNA and DNA sequencing and integrated optoelectronic circuits etc. While for their practical applications, control and optimization of the parameters are of great significance and have been attracting growing interests in the past years. Here I will present our recent work on the key parameters control and optimization about semiconductor nanowire light emitting devices, including efficiency enhancement, wavelength control, mode optimization, threshold reduction and polarization modulation. The work pioneered in nanosale light field may provide a way of fabricating ultra-compact nanophotonic devices and may find its applications in single molecule detection, integrated optical circuits, and optical communications etc.
