Abstract:
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.
