Current Research Projects
High-Power Fiber Lasers
In this project we will develop a novel approach to the design and fabrication of high power photonic bandgap fiber lasers based on the hollow dielectric fiber which have recently developed at MIT. While focusing on a particular wavelength in the visible or NIR spectral regime we anticipate that the methodology developed under this program will be general and can be applied to various wavelengths. We will incorporate novel gain medium such as SnS2 nanocrystals which are currently being developed at MIT into our photonic band gap structures which will provide the optical feedback.

Long-Distance, High Data-Rate Quantum Communication with Ultra-low Loss Photonic Band Gap Fiber
The discovery of the omnidirectional reflection criteria has opened new possibilities for guiding and localizing light. In particular a novel all-dielectric hollow fiber has been designed and fabricated which guides light in air. Recent theoretical analysis has predicted extremely low propagation loss characteristics for this fiber. The objectives of this study are to: 1) Expand the theoretical understanding of the system and the relations between the physical structure and the electromagnetic modes supported by it. 2) Identify and synthesize glasses which have substantially disparate indices of refraction yet similar thermo-mechanical properties which can be thermally co-processed. This project will make use of the state-of-the-art optical fiber draw tower which we have recently constructed at MIT. The fibers will be designed to enable a long distance high data-rate quantum communication system.
