07/09/2008

Ranojoy Bose, ME PhD Student, received the 2008 IEEE (Institute of Electrical and Electronics Engineers) Graduate Student Fellowship. The IEEE Lasers & Electro-Optics Society (LEOS) established the Program to provide Graduate Fellowships to outstanding LEOS student members pursuing graduate education within the LEOS field of interest (electro-optics, lasers, photonics, optics, or closely related fields).

Ranojoy's research focus is the study of lead sulfide nanocrystals integrated in silicon photonic crystal nano-devices for near-infrared single-photon source applications. Photonic crystal cavities are micro/nano-structures that allow for remarkable confinement of photons at engineered wavelengths. Ranojoy explains, "This allows us to explore many exciting physical applications, for example, the modification of emission from nanocrystal quantum dots in the photonic crystal cavity environment. My work involves the design as well as layout/fabrication of the devices, quantum dot integration, and advanced spectroscopy measurements". He has also explored Förster energy transfer in lead sulfide nanocrystals near 1550 nm wavelengths and demonstrated highly-efficient non-radiative resonant energy transfer in monodisperse quantum-dot assemblies. In this experiment, energy transfer can occur between neighboring quantum dots on the basis of their energy structure and spatial proximity. "We believe that this mechanism has promising applications in novel solar-cells based on quantum dot technology, as well as ultra-fast quantum communication," he concluded.

Ranojoy expressed gratitude to his advisor, Prof. Chee Wei Wong, Prof. Tony Heinz, and the ME department for their support in this study and the fellowship award.
