Abstract:

Realizing the integration of nanostructures into useful devices and photonic systems has been a topic in hot pursuit for almost a decade. While many groups demonstrate innovative synthesis techniques and compelling device possibilities, true utility has not yet been realized. In this work, we focus on photolithographically defined nanopillars: the diameter, pitch and mask arrangement can be precisely pre-determined at nanometric resolution. Our approach, in contrast to catalyzed synthesis, allows exquisite control of material composition and doping thus enabling the possibility of competitive device realization. This presentation includes discussion of application driven device design based in nanostructures and plasmonics. Device demonstrations include hybrid photovoltaics, room-temperature, nanobeam lasers and plasmonic-enhanced single-photon avalanche photodetectors (SPAD) featuring self-aligned subwavelength metal grating.
