The properties of a metastable defect observed in n-InP are reviewed. This defect is bistable and it has been established that one of its configurations has negative U character.

A classic theorem of vanderWaerden asserts that for any positive integer k, there is an integer W(k) with the property that if W >- W(k) and the set {1, 2,...,W} is partitioned into r classes C

Analysis of IR and laser induced fluorescence spectra of naphthazarin in rare gas matrices shows clearly that its vibrational potential is characterized by well localized, deep, C2v potential minim

We consider a system with N unit-service-rate queues in tandem, with exogenous arrivals of rate at queue 1, under a back-pressure (MaxWeight) algorithm: service at queue n is blocked unless its qu

We show how the grating diffraction properties of a NxN waveguide grating router (WGR) can limit the size of N when the device operates with a unique set of N wavelengths as a strict-sense non-bloc

The material gain of equal width InGaAsP/InGaAsP multi-quantum well active layers is calculated solving the Luttinger-Kohn Hamiltonian, including tetragonal strain and confinement effects.

We have recently completed a series of experiments which indicates that we can build neural networks many times larger than have been previously attempted.

We show that doped-fiber amplifiers operated in saturation can display very fast transient dynamics and large power swings in a packet switching environment with highly variable packet interarrival

We simultaneously measure the intensity modulation level and the optical spectrum of the output of an MQW modulator, and use these data to deduce the electro-optic coefficients.

Third-order Kerr nonlinearities and Raman gain are studied experimentally in high purity As2Se3 optical fibers for wavelengths near 1.55 mum.
