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.

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.

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 ...

Wavelength-Selective Devices

2001
A single optical fibre is capable of transporting multiple signals, each at its own wavelength. At the fibre entrance, the signals fed by a number of transmitters, each operating at a specific wavelength, are combined by a wavelength multiplexer and launched into the transmission fibre. At the fibre exit, a wavelength demultiplexer routes these signals
