The Stylus NanoProfilometer is a tool that provides nondestructive profilometry of structures encountered in semiconductor manufacture. Results from scans of photoresist and photomasks are shown.

The method of restricting longitudinal flow in oil impregnated cables by employment of styrene joints was primarily developed in connexion with life tests on short lengths of cable.

A Lie group theoretical approach to the analysis of interferometers is presented. Conventional interferometers such as the Mach- Zehnder and Fabry-Perot can be characterized by SU(2).

This paper reports on a continuation of previous work on the digital coding of 7 kHz wideband audio at 56 kb/s.

In this paper we present a sub-band coder for true color images that uses an empirically derived perceptual masking model to set the allowable quantization noise-level not only for each sub-band bu

We investigate generation and detection of signals with baudrate above the DAC and ADC sampling rates.

We investigate generation and detection of signals with baudrate well above the DAC and ADC sampling rates for 200-Gbps applications.

As optical transceivers evolve towards 200G per lane, the comparatively low bandwidth and sampling speed of the commercially available high-speed DACs and ADCs increasingly become the dominating ob

We observe that the formation of low angle grain boundaries (sub-boundaries) depends strongly on the thickness of the recrystallized Si film.

We characterize a strongly anisotropic waveguide consisting of alternating 80 nm layers of n(+)-InGaAs and i-AlInAs on InP substrate.
