Compound semiconductor oxide antireflection coatings

May 15, 2000
Author(s)
K. J. Knopp, Richard Mirin, Kristine A. Bertness, Kevin L. Silverman, David H. Christensen
We report the development of high quality, broad-bandwidth, antireflection (AR) coatings using the low index provided by wet thermally oxidized Al 0.98Ga 0.02As. We address the design criteria, fabrication, and characterizations of AR coatings composed of

Vibrationally-Resolved Sum-Frequency Generation With Broad Bandwidth Infrared Pulses

October 15, 1998
Author(s)
Lee J. Richter, T Petralli-Mallow, John C. Stephenson
We present a novel procedure for vibrationally-resolved sum-frequency generation (SFG) in which a broad-bandwidth IR pulse is mixed with a narrow-bandwidth visible pulse. The resultant SFG spectrum is dispersed with a spectrograph and detected in parallel

Optical trapping of selected dielectric microparticles in air

Author(s)
Haesung Park, Thomas W. LeBrun
We demonstrate a method to trap a selected dielectric microparticle in air using radiation pressure from a single-beam gradient optical trap. Randomly scattered dielectric microparticles adhered to a glass substrate are momentarily detached using
