    Notes: Abstract. Copper single-crystals are grown by a galvanic method, using etched ion tracks in a polymer foil as templates. The copper deposition is carried out by reversible pulse electrolysis in an ultrasonic field. The method applied for this purpose permits fabrication of stable standing cylindrical single crystals with diameters in the nanometer and micrometer range with high aspect ratio and density of 105–107 per cm2 on a large area. The experimental results obtained in this way are compared with the results obtained by direct current plating under ultrasonic treatment and sole reversible electrolysis. The effects of all these deposition processes on the structure of copper claddings are shown.

    Notes: Abstract A saturation-spectroscopy experiment is performed in a three-level system in Xe I, and shows that a narrow dip occurs in the power-broadened Lorentzian response. It is due to the Zeeman splitting of common level by the earth magnetic field. Other splittings, typically larger than 0.2 the natural width, can be observed using this saturation effect. Interpretation is made on the basis of simple realistic assumptions.

    Notes: Abstract Laser induced nonlinear absorption profiles in a three-level system have been recorded to study the effect of elastic collisions upon optical coherences. In our particular system, the signal is due to a pure double-quantum term, where we have separated the effect of phase-interrupting collisions from the effect of velocity-changing collisions. Experimental results show that the effect of velocity-changing collisions is very small, and that broadening of the signal is due to phase-interrupting collisions mainly. We are able to determine the increase of the decay rate of the coherent superposition (the “coherence”) of two levels of same parity [Dγ 13/dp=(6.5±1) MHz/Torr] and an upper limit for the mean velocity change (ũ≲5m/s).

    Notes: Abstract The high precision accelerometer consists of 5 silicon wafers and packages by silicon fusion bonding. The sensor has a capacitance measuring principle and works in an open loop or closed loop operation mode. The etching process for the realization of thin beams and seismic mass, the silicon fusion bonding and the metallization process are described.

    Notes: Abstract This project develops an electro-optical board technology based on the combination of discrete wiring and glass optical fibers. Such a board provides optical parallel interconnects. Meaning that 16 optical fibers will be led simultaneously in and out the board from the incomming links to the transmitter and receiver modules mounted on this board. This technology is expected to fulfil the needs of next generation broadband exchanges concerning high data rate flow. As the ligning-up of the fibers requires severe dimensional tolerances, we have to enter the field of the micromechanica. The most critical parts will therefore be manufactured with the LIGA technique. The first generation of models produced and tested by Alcatel Bell Telephone proved that this concept is perfectly feasible.
