The laser of choice for military directed-energy-weapons (DEW) research has traditionally been the chemical ­laser.

The industry standard for the determination of refractive-index profiles for axially symmetric optical fibers is the refracted-near-field (RNF) technique.

Building on an earlier demonstration of quantum-dots-in-a-well (DWELL) detectors that sense multiple wavelengths in the middle-wavelength infrared (MWIR) and in the longer-wave...

Laser cooling of atoms has led to some striking advances in physics research, including the first demonstration of “slow light,” in which a cloud of 50-μK sodium atoms in a degenerate...

The challenge for optical interconnects is to span shorter distances at higher speeds, with signals sent through many parallel fibers or waveguides.

Surface plasmons propagate along the interface between a conductor and a nonconductor or dielectric; they are bound to the interface and exponentially decay in both media.

Although gravitational waves-ripples in the space-time continuum due to moving matter-have never been detected, the Large Scale Cryogenic Gravitational Wave Telescope (LCGT; Honshu...

Whether you’re a researcher, engineer, or manager interested in the application of lasers and optoelectronics to materials processing, defense and security, medicine, communications...

In August of 1955, 74 individuals attended the first formal meeting of SPIE-Society of Photo-Optical Instrumentation Engineers in Hollywood, CA, to exchange ideas and discuss ...

With high thermal conductivity and resistance to damage, carbon-nanotube coatings are a promising new technology for thermal detectors.

The point-spread function (PSF) of an optical system can be altered by inserting a spatially varying filter at the pupil plane; if the filter is properly designed, the width of...
