Optical wavelength-routed networks enable parallel transmission of massive datasets on non-overlapping wavelength channels. However, as the sizes of scientific workflows increase, the simple availability of multi-wavelength resources will fall short of supporting application needs. Rather, these resources must be allocated intelligently, efficiently, and flexibly to bear the burden of high-volume...
We present both experimental and theoretical investigations of the so-called reverse emission state dynamics in a two-section InAs/InGaAs Quantum Dot (QD) laser. In contrast to the classical state scenario, we demonstrate by properly designing the laser cavity and the QD active region, a reversal of the emission state transition: At a certain gain current Excited-state (ES) lasing and mode-locking...
We report time-resolved linewidth measurements of different sizes of optical packets under wavelength-switching for the first time and show that laser linewidth is significantly broadened during switching transition requiring ~3 mus to attain its minimum value.
In this article we assess the economic gain obtained by introducing multi-granularity switching optical cross-connects (MG-OXCs) in an optical transport network. An MG-OXC is an equipment able to switch wavelengths, to aggregate (disaggregate) wavelengths into (from) groups of wavelengths called wavebands and to switch wavebands. We evaluate the economic gain by comparing the cost of instantiating...
1-ms wavelength-switching in a mid-infrared range was achieved by difference-frequency mixing in an In-doped AgGaS/sub 2/ crystal. Tuning range was shifted to a longer wavelength region maintaining noncritical phase-matching with increase of indium concentration.
