Molecular imprinting is a novel way to create sensitive layers for chemical sensors. Polymers can be moulded with analyte molecules, the template, which generate cavities in the polymer matrix that are capable of selectively incorporating the analyte

The air quality in the domestic area, workshops or industrial work places is of great interest, especially in respect to humidity and vapors. The simplest way to determine humidity is by resistive measurements using interdigital transducers (IDT). Co

High-speed switching capabilities are demonstrated for an InP/InGaAsP optical injection-type directional coupler switch. Equal rise and fall times of 2 ns are achieved at low switching currents of only 10 mA. Modulation of the switch with pulses betw

The carrier induced refractive-index change Δn in integrated InGaAsP 1.30 μm interferometer structures is evaluated by 1.55 μm transmission measurements. At carrier concentration N from 8×10 16 /cm 3 to 3×10 18 /cm 3 a value of Δn/N=-1×10 -20

Optical InP/GaInAsP directional coupler switches with a total length of 2 mm have been fabricated and operated by carrier injection. Switching is achieved at a very low injection current of 4 mA. For both switching states a crosstalk suppression exce

The usual way to align a liquid crystal layer homogeneously is rubbing the substrate, wherby micro-grooves are produced. We investigated the orienting influence of micro-grooves of variable density using different substrate materials and different li

In dielectrically positive mixtures of the nematic N4 with cholesteryl-chloride an unusual texture transition was observed which can be applied in a storage effect. The variation of several characteristic parameters of these mixtures with concentrati
