Research Overview

The Bahl Research Group performs experimental research at the interface between optical and mechanical systems. Of particular interest are the mechanisms by which light interacts mechanically with photonic microdevices (i.e. via radiation pressure, gradient force, electrostrictive pressure, and photothermal effects), and how mechanical devices can affect and manipulate light.

See Research for more details.


Positions

We are always on the lookout for graduate and undergraduate researchers with background in the following topics -- electromagnetics, photonics, microfabrication, material physics, nonlinear optics, MEMS and NEMS, and circuit design. Experimental experience is strongly preferred. Interested students must already be admitted to UIUC and should contact Prof. Bahl with a complete CV highlighting relevant experience.
