Optomechanical systems are currently of great interest as they lie on the boundary between quantum and classical physics, promising fundamental insights as well as new technologies. Most of the work in optomechanics has been based on the fact that photons carry linear momentum. In this talk, two systems involving the use of orbital angular momentum in optomechanics will be presented. The first system will involve the rotational analog of the familiar Fabry-Perot cavity. A second system will be presented as a platform for the storage of photons carrying orbital angular momentum in a surface shear acoustic wave.


Mishkat Bhattacharya obtained his PhD from the University of Rochester in 2004. After stints at Georgia Tech, the University of Arizona, and the University of Maryland at College Park, he joined RIT in 2011.
