A major challenge to increasing bandwidth in optical telecommunications is to encode electronic signals onto a lightwave carrier by modulating the light up to very fast rates.

Summary form only given. The rapid progress in communications requires high capacity optical communication systems that are limited by the bandwidth of optical amplifiers.

New transmission systems which employ binary pulses and regeneration1 require pulses which are a few millimicroseconds in length.

We present the realizations of an array of Distributed Feedback (DFB) lasers and passive optical waveguides based on Silicon.

We demonstrate a novel optically broadband polarization controller that allows automatic reset-free polarization transformation from any varying general input polarization state into any general ou

A broadband single pole double throw (SPDT) switch has been developed for use in the range of 0 to 30 GHz.

Broadband (500 cm sup (-1)) infrared pulses of 350 fs duration tunable from 2.5-5.5microns have been produced by difference frequency mixing in LiIO sub 3 and used to do subpicosecond time-resolved

In this paper we describe the concept of broadcast and multicast (BCMC) transmission over HSDPA, a shared high-speed packet data channel on the downlink defined in the UMTS standard.

We consider a MIMO (linear Gaussian) channel where the inputs are turned on and off at random, and the outputs are sampled at random with probability p.

We investigate the estimation of the size of a broadcast audience. We give the Maximum Likelihood estimators for different scenarios.
