Using self-phase modulation, the nonlinear index of refraction for ten different types of optical fiber has been measured.

We have measured the nonlinear refractive index (n sub 2) of single-crystalline PTS-polydiacelylene channel waveguides at 1.06microns using two different techniques.

Stimulated emission, obtainable at high optical pumping levels, has been used to follow the pressure dependence of the I-band gap of molecular beam epitaxial In sub 0.53 Ga sub 0.47 As on (001) InP

We measure the shot-to-shot slip of the carrier-envelope phase (CEP) of mode-locked femtosecond laser pulses by using a 2f-to-f self-referencing interferometer.

The Wigner function of a train of ultrashort optical pulses is reconstructed from a large set of completely characterized individual pulse sub-trains obtained using Spectral Phase Interferometry fo

We present the magneto-optic method to measure the local birefringence of single-mode fibers.

The surface voltage profile of an avalanche photodiode has been measured by monitoring the energy shift of the indium MNN Auger transition in a scanning Auger microprobe.

Thermal expansion coefficients and biaxial elastic moduli of the sputtered W, WN sub x, WSi sub 0.45, and WSi sub 0.67 N sub 0.10 thin films, used as refractory gate in the self-aligned MESFETs on

The effect of 30 ns, 6943angstroms high power laser irradiation on the surface properties of pristine and ion implanted highly oriented pyrolytic graphite (HOPG) has been studied.

Source and drain series resistance becomes significant in submicron channel length MOSFET's and can cause large errors in traditional methods for transistor characterization.
