Behavior of distributed wavelength provisioning in wavelength-routed networks with partial wavelength conversion [PDF]
IEEE INFOCOM 2003. Twenty-second Annual Joint Conference of the IEEE Computer and Communications Societies (IEEE Cat. No.03CH37428), 2004 Distributed wavelength provisioning is becoming one of the most important technologies for supporting the next-generation wavelength-routed networks. In this paper we analyze the behavior of wavelength-routed networks with partial wavelength conversion capabilities (i.e., where wavelength conversion is available at only a subset of network nodes) when ...

On the effective wavelength in two-wavelength interferometry
Pure and Applied Optics: Journal of the European Optical Society Part A, 1998A discussion on the effective wavelength in two-wavelength interferometry is given. A definition, different from the commonly adopted one, is presented and its validity is discussed. By adopting this new effective wavelength the range over which lengths can be measured using interferometric techniques can be vastly increased, without introducing phase ...

Angewandte Chemie, 2019
Small-molecule organic fluorophores, spectrally active in the 900-1700 nm region, with tunable wavelength and sensing properties are sought-after for in vivo optical imaging and biosensing. A panel of fluorescent dyes (CX) has been developed to meet this

Logarithmic wavelength demultiplexers
Journal of Lightwave Technology, 2003A general approach for a full 1 /spl times/ N demultiplexer using a tree of filter stages is proposed. The device architecture is compact, requiring at least N - 1 filter stages, and flexible, as each filter stage can be arbitrarily designed, with the only constraint of the half-band power property.

An entanglement-based wavelength-multiplexed quantum communication network
Nature, 2018Quantum key distribution1 has reached the level of maturity required for deployment in real-world scenarios2–6. It has previously been shown to operate alongside classical communication in the same telecommunication fibre7–9 and over long distances in ...

Wavelength channel bandwidth of wavelength-selective devices [PDF]
Journal of Shanghai University (English Edition), 2001 Narrow bandwidth is a crucial factor in a high-performance wavelength-selective device (WSD). There are many different expressions to estimate bandwidths of many different WSDs. In this paper, we derive an important rule that the differential time delay between two coupling modes is the most important factor deciding the wavelength channel bandwidth ...

Psychoanalytic Psychotherapy, 1993
In this paper I have endeavoured to draw attention to what is meant when we refer to a patient as psychotic. It is argued that it is not enough just to be ordinarily sensitive to our patients; we need to tune into the psychotic wavelength with all its implications for understanding and management. Illustrative case‐histories are presented from everyday

Wavelength Reservation in Wavelength-routed Optical Networks
Journal of Optical Communications, 2006A novel wavelength reservation protocol is proposed for wavelength-continuous lightpaths establishment in the wavelength-routed optical networks. The protocol uses backward reservation protocol (BRP) with intermediate retry to reduce the chance of blocking.

Wavelength-selective photodetectors operating at long wavelength
SPIE Proceedings, 2006We demonstrate a wavelength-selective photodetector that combines a Fabry-Perot filtering-cavity (FPC) with a taper absorption-cavity (TAC). The taper cavity shows non-resonant effect but exhibits absorption enhancement effect, so that high-speed, high quantum efficiency, wide tuning range and ultra-narrow spectral linewidth can be achieved ...
