We present new methods for the in situ fabrication of novel device structures based on the epitaxial shadow mask (ESM) MBE technique. For high-quality selective contacts, the deposition of the dopants must exactly be aligned to the angular position o

Ordered GaInP shows a strong polarization anisotropy of the Franz–Keldysh absorption. Polarization-dependent electroabsorption measurements provide a powerful tool to obtain information about the valence band structure of ordered material. The meas

Excellent selective n- and p-contacts to highly doped and closely adjacent layers in n-i-p-i doping superlattices can be fabricated using the epitaxial shadow mask molecular beam epitaxy (ESM-MBE). With this method the growth within the window of a G

We report on the dynamic operation characteristics of a novel monolithic waveguide-based smart pixel. In this smart pixel, two surface-normal optical input beams control an optical output beam propagating in-plane through a waveguide modulator. For t

We demonstrate a novel and simple smart pixel which combines free space optics for the input signal and waveguide configuration for the output beam. Our monolithic smart pixels consist of a threshold switch with high photoconductive gain and a Franz

Optical switching with gain realised with monolithic waveguide-based smart pixels is reported. In this smart pixel a high-power light beam propagating in a waveguide structure is controlled by small surface-normal optical input beams incident on a re
Large calcium fluoride (CaF/sub 2/) single crystals are required for the fabrication of lenses in the so-called wafer-steppers of future IC- lithography technologies operating at 193 nm and 157 nm. Numerical simulation plays an important role in desi
