Technological developments for microwave and opto-electronics

We are living now in an exciting period in which advances of technology enable the construction of a new generation of devices and circuits, making the dream of an "intelligent world" feasible. The realisation of this aim is possible by developing all the communication systems, from satellite, through long range optical fibre, to short range mobile phones and the last meter links, which provide communication between human beings and intelligent objects. To make this happen, a further dynamic development of technology is needed. Emerging technologies like submicrometre electronics, nanotechnology, microsystems, blue and UV opto-electronics and THz electronics have to be further developed and strongly linked with medical sciences and biotechnology. An interdisciplinary approach is a must. The paper reviews the latest technology developments which can make this vision reality.
