Wavelength calibration methods in laser wavelength measurement

Applied Optics, 2021
At present, accurate wavelength calibration plays an important role in laser spectrum measurements. Although the wavelength calibration methods have been investigated for a long time, there are no techniques that are particularly designed for laser spectral calibration to the best of our knowledge.

Behavior of distributed wavelength provisioning in wavelength-routed networks with partial wavelength conversion [PDF]

open access: possibleIEEE 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 ...

Optical Constants of Water in the 200-nm to 200-microm Wavelength Region.

Applied Optics, 1973
Extinction coefficients k(lambda) for water at 25 degrees C were determined through a broad spectral region by manually smoothing a point by point graph of k(lambda) vs wavelength lambda that was plotted for data obtained from a review of the scientific ...

On their wavelength [PDF]

open access: possibleEarly Years Educator, 2019
National Radio Day is celebrated in the US on 20 August 2019 and is not only a day to remember the invention of the radio but also to think about words and sound as a medium of communication.

On the effective wavelength in two-wavelength interferometry

Pure and Applied Optics: Journal of the European Optical Society Part A, 1998
A 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 ...

Stable, Wavelength-Tunable Fluorescent Dyes in the NIR-II Region for In Vivo High-Contrast Bioimaging and Multiplexed Biosensing.

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

An entanglement-based wavelength-multiplexed quantum communication network

Nature, 2018
Quantum 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 ...

Logarithmic wavelength demultiplexers

Journal of Lightwave Technology, 2003
A 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.

Wavelength channel bandwidth of wavelength-selective devices [PDF]

open access: possibleJournal 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 ...

The psychotic wavelength

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
