The fabrication and performance characteristics of a thermoelectrically tunable single-wavelength integrated external cavity distributed Bragg reflector laser are described.

A new method for fabrication of tunable InGaAsP-InP single-mode lasers without epitaxial overgrowth is reported.

A monolithically integrated tuneable photonic source designed for the generation and modulation of millimetre-wave signals is demonstrated up to 120 GHz.

We present a monolithically integrated silicon-photonics 10-channel VOA-MUX (variable optical attenuators with multiplexing filters) with on-chip power monitors.

In a (t,n,m,)-multi-partioning problem we partition t lists of nm ordered numbers into n sets, where each set contains m numbers from each list.

Monotonicity and continuity are important qualitative properties of stochastic discrete event systems, such as networks of queues.

By viewing networks of queues, and other stochastic systems, as generalized semi-Markov processes, we obtain simple, general conditions for stochastic monotonicity.

We study multi-dimensional stochastic processes that arise in queueing models used in the performance evaluation of wired and wireless networks.

We present the outline of an IBM 7090 machine-program for the Monte Carlo estimation of the percolation probability for a variety of space lattices. The underlying theory is briefly summarized.

A Monte Carlo method, implemented for quantifying confidence bounds on thermoreflectance (TR) measurements of interfacial thermal conductance G at solid-liquid interfaces modified with self-assembl
