Impact of multi-wavelength sliceable transponders in elastic optical networks [PDF]

, 2015
The utilization of sliceable bandwidth variable transponders based on multi-wavelength technology is evaluated in EONs. A routing and spectrum assignment scheme is proposed specifically designed to consider the constraints introduced by multi-wavelength ...

Multi-wavelength Optical Approach for Non-invasive Alcohol Detection [PDF]

한국정밀공학회지
Alcohol acts as a central nervous system depressant and is classified as a psychoactive drug that impairs cognitive alertness and motor coordination. Driving after alcohol consumption slows reaction time in emergency situations and increases the risk of ...

Multi-Wavelength Photoacoustic Temperature Feedback Based Photothermal Therapy Method and System

Pharmaceutics, 2023
Photothermal therapy (PTT) is a new type of tumor treatment technology that is noninvasive, repeatable, and does not involve radiation. Owing to the lack of real-time and accurate noninvasive temperature measurement technology in current PTT surgical ...

Multi-wavelength spectrophotometry of EX Hydrae [PDF]

Astronomy & Astrophysics, 2002
We present phase-resolved infrared and optical spectrophotometry of the intermediate polar EX Hya supplemented by archival ultraviolet data. The spin-modulated emission from the accretion funnel and the emission from the accretion disk or ring contain substantial optically thin components.

Multi-wavelength selective crossbar switch

Optics Express, 2019
Here we demonstrate an 8x4 multi-wavelength selective ring resonator based crossbar switch matrix implemented in a 220-nm silicon photonics foundry for interconnecting electronic packet switches in scalable data centers. This switch design can dynamically assign up to two wavelength channels for any port-port connection, providing almost full ...

Multi-wavelength reflection spectra from an acousto-optic modulated fiber Bragg grating in a highly birefringent suspended core fiber [PDF]

, 2017
The interaction of a fiber Bragg grating and longitudinal acoustic waves in a highly birefringent suspended-core fiber is investigated for the realization of a multi-wavelength reflection property.

Multi-wavelength and polarimetric observations of Sagittarius A*

Journal of Physics: Conference Series, 2006
We summarize the results of some of the latest NIR/sub-millimeter/X-ray observing campaigns. Those include the latest simultaneous observations as well as the most recent results from VLT NACO observations of polarized NIR, flare emission of Sgr A*. We interpret the new NIR, polarimetry results using a model in which spots are on relativistic orbits ...

Realization of Raman amplifier with reverse multi - wavelength pumping

Tongxin xuebao, 2006
A fiber Raman amplifier with bandwidth of 90 nm using eight pump lasers was presented. Based on the theoretic model, a gain of （11.5±1） dB was obtained with the 25 km SMF manufactured by Corning Corp as gain media.

Snapshot multi-wavelength interference microscope

Optics Express, 2018
A snapshot multi-wavelength interference microscope is proposed for high-speed measurement of large vertical range discontinuous microstructures and surface roughness. A polarization CMOS camera with a linear micro-polarizer array and Bayer filter accomplishes snapshot multi-wavelength phase-shifting measurement.
