A steady-state model of a strained MQW-SOA is described.

This paper introduces a method of wideband system identification that uses a uniformly-spaced set of tones with allpass filters and square- law detectors to obtain estimates of amplitude and phase

The rapid growth of wireless voice subscribers; the growth of the Internet; and the increasing use of portable computing devices suggest that wireless Internet access will rise rapidly over the nex

Lightguides connecting remote customer stations to a central switching office would make wideband telecommunications available to large markets.

A five-carrier supperchannel with probabilistically shaped PDM 256-QAM symbols is experimentally demonstrated.

We report the development of a current-controlled widely tunable laser diode based on InP with photonic crystal mirrors and an integrated amplifier section for stabilized power output.

We have integrated a broadly tunable grating-assisted vertical coupler as an intracavity filter to demonstrate a novel, monolithic InGaAsP/InP extended-cavity laser with measured electrical tuning

The authors report the realization of a new type of long-period fiber gratings with enhanced temperature sensitivity of 80 nm/100C via the use of specially designed fiber structures incorporating p

Using parametric amplification in a highly nonlinear fibre, we demonstrate a widely tunable modelocked multiwavelength ring laser generating up to six simultaneous modes with 4.4 ps pulse width at

We fabricate tunable semiconductor lasers with two coupled photonic crystal cavities that allow up to 46 nm tuning range with a side-mode suppression ratio greater than 30 db.
