Research Interest

Nano-Photonic devices for telecommunication and sensing

Regardless of the specific application, the key requirements from any optical system are compactness and low loss. Nano-scale optical components enable the realization of dense, highly functional integrated optical circuits while low-loss improves the efficiency and performances of the system. Our research is focused on achieving these characteristics by developing novel wave guiding concepts and optical materials. Currently there we are working in two main directions. The first direction is achieving tight confinement of light using distributed feedback. The objective is to develop components such as waveguides, resonators etc. that are capable of confining light in sub-micron dimensions. The applications are ultra-dense photonic processors for telecom and sensing applications. The second project deals with the development of new optical polymeric materials and soft-lithography molding methods capable of fabricating nanometer-scale features.

Our results so far include the demonstration of the world smallest semiconductor laser, an ultra-sensitive biochemical sensor and a novel tunable reflector based on electro-optic polymer micro-cavities. In the future we intend to expand our activity to 3D polymeric nano-photonic components and integration of sensor-arrays with micro-fluidic channels.
