overview

My research interests are in nano-optics and nano-electronics: materials & devices; hierarchical integration of nanoscale structures into systems for multifunctional operations. Single quantum-dot light sources for quantum information processing. Metal nano-lenses for sub-diffraction-limited beam shaping and negative-angle refractive optics. Study of plasmonic phenomena as a possible gateway to merging optics with electronics and overcoming their limits; nano-plasmonics for nanosystems-on-a-chip for energy-efficient, large-bandwidth computing/communications; low-loss plasmonic metamaterials for quantum photonic integrated circuits. Nanoscale vacuum electronics: low-voltage emission of 2D electron gas; use of nanoscale void (air) channel as a medium for ultrafast transport of electrons; nano-vacuum transistors and circuits for extreme environments.
