Research

Laser-controlled Millimeter-Wave directional couplers in image guide technology

For applications in the millimeter-wave range the propagation characteristics of layered image guides in a quartz-silicon-sandwich structure can be controlled by means of cw or pulse modulated optical excitation. Furthermore, passive components like phase shifters, attenuators, switches, filters, antennas, and couplers based on dielectric image guides in conjunction with photosensitive semiconductor material can be controlled optoelectronically as well. The coupling characteristics of waveguide couplers, aperture couplers, and beam-splitter-type couplers in image guide technology are investigated theoretically and experimentally at W-band frequencies. Regarding the coupling of the structure, a high optoelectronic sensitivity is desirable whereas VSWR of the main- and sub-line as well as optically induced losses should be kept at a minimum.
