Monolithic integration of various kinds of optical components on a silicon wafer is the key to making silicon (Si) photonics practical technology. Applying silicon photonics to telecommunications further requires low insertion loss and polarization independence. We propose an integration concept for telecommunications based on Si and related materials and demonstrate monolithic integration of p...

This paper introduces the concept of a Telecommunications Enhanced Community (TEC). The TEC is a community which has a variable mix of real and telecommunications services for reasons of community sustainability. Some telecommunications services may be dispensed with if a population increase results from successful implementation. We examine a number of theories that can support such a concept ...

The predicted expansion of the telecommunications market in Europe will place a premium upon the ability of providers of telecommunications services to efficiently configure systems that satisfy their customers' needs. The complexity of the domain will mean that configuration by hand will not be an efficient solution, and some kind of computer-based support will be required. In this paper we de...
