Nanoscale Photonics

My research explores use of single molecules as nanoscale materials for photonics and optoelectronics applications. Our specific focus area exploits ink-jet printing techniques for generating uniformly z-oriented semiconducting polymer nanostructures with a number of interesting optical properties. We are currently exploring photonic quantum information processing applications of these novel species.

Research Interest Potential Application
Polymer-based nanophotonics Single-photon based opto-electronic devices
Optical spectroscopy of nanoscale confined systems Guiding design of novel organic systems for photonics applications
Single-molecule optoelectronics Generation of electrically-pumped single-photon source
Single-molecule/nanoparticle spatial manipulation Molecular sorting and development of nanoscale phased-antenna arrays
