Optomechanical Detection of Light with Orbital Angular Momentum
Hamidreza Kaviani, Roohollah Ghobadi, Bishnupada Behera +5
We present an optomechanical device designed to allow optical transduction of orbital angular momentum of light. An optically induced twist imparted on the device by light is detec…
Fast carrier dynamics in GaAs photonic crystals near the material band edge at room temperature
Ranojoy Bose, Jason S. Pelc, Charles M. Santori +2
We measure fast carrier decay rates (6 ps) in GaAs photonic crystal cavities with resonances near the GaAs bandgap energy at room temperature using a pump-probe measurement. Carrie…
Picosecond all-optical switching in hydrogenated amorphous silicon microring resonators
Jason S. Pelc, Kelley Rivoire, Sonny Vo +3
We utilize cross-phase modulation to observe all-optical switching in microring resonators fabricated with hydrogenated amorphous silicon (a-Si:H). Using 2.7-ps pulses from a mode-…
Adsorption properties and third sound propagation in superfluid He films on carbon nanotubes
Sonny Vo, Hossein Fard, Anshul Kogar +1
We consider the adsorption properties of superfluid He films on carbon nanotubes. One major factor in the adsorption is the surface tension force arising from the very small di…
