In this paper we present some results concerning the accuracy with which a numerical solution of the system of ordinary differential equations x + J(x, 0 = 0 , t ^ 0 [x(0) = xo] (1) can be obtained

We describe an algorithm and its implementation to transmit two TV signals over a 45 Mbit/s channel.

The present article contains the description of two types of wide band interconnections used as package feedthroughs.

We have discovered that below bandgap photoexcitation produces large bleaching of the exciton absorption in GaAs quantum well heterostructures.

A GaAs/AlGaAs waveguide photodetector combining disordered and as-grown quantum well photodiodes is described.

A new method of simultaneous two way transmission over one fiber is described. Only one optical source is required when an electrooptical modulator is used.

D.L. Dexter's contributions to the theory of two-center electronic and vibronic transitions are reviewed.

We report the development of a tunable laser diode array monolithically integrated with a Y-coupler structure based on photonic crystals.

We report the generation and characterisation of soliton-molecules in a fibre laser, in which two different frequencies have common group velocities and (negative) dispersion.

A two-dimensional array of 10x10 diffractive lenslets was fabricated and tested. Each lenslet has a rectangular aperture and a size of 1.5 mm x 1.5 mm.
