A black box model is derived for an erbium-doped optical amplifier and is successfully applied to 1480 and 980 nm pumped devices operated under conditions which are typical for wavelength division multiplex (WDM) systems. It allows compound optical a

A yield and cost model for integrated optical chips is presented on the basis of easily attainable figures. It allows a prediction to be made of yield and cost for complex optical chips on the basis of currently available processing technology. Both

Some key results of a benchmark test, initiated in 1992 by the Working Group 2 of COST Project 240 at a modelling workshop in Teupitz, Germany, are presented. A great number of BPM algorithms, such as the FTBPM, various types of FDBPMs, wide angle ap

The theory of planar spectrographs is presented. It is proven that by no means all aberrations up to the order of x/sup 4/ can be corrected over a finite spectral range. A general procedure to construct gratings with two stigmatic points of (nearly)

Using the routine Papanicolaou test for grouping, 35 normal and 148 abnormal cervical smears were screened by fluorescent in situ cytohybridization for Epstein-Barr (EBV) and human cytomegalovirus (HCMV). Viral presence was detected in 55% of all hyb

A thermooptically tunable optical phased array in the SiO/sub 2/-Si material which allows forward and backward tuning, was successfully demonstrated. By imprinting grooves into the substrate it was possible to achieve a tuning efficiency of 2 nm/W an

Calculated and measured properties of InGaAsP/InP waveguides are compared. The spectral response of Bragg gratings was used to measure precisely the effective indexes of the guided modes of InGaAsP/InP waveguides. The shape of the near fields and the
