IET Communications, 2007 The multicast wavelength assignment problem in wavelength-routed wavelength- division multiplexing networks with limited wavelength conversions is addressed. A new multi- wavelength multicast wavelength assignment (MMWA) algorithm has been developed based on the multi-wavelength assignment strategy, by allowing multiple available wavelengths in a link ...

Excitation wavelength independent visible color emission of carbon dots.
Nanoscale, 2017 Carbon dots (CDs) usually emit a strong blue light and excitation wavelength dependent long wavelength lights. This significantly limits their applications because one has to use a series of different excitation light sources to get different colors and ...

Single Photon Adiabatic Wavelength Conversion [PDF]
, 2012 Adiabatic wavelength conversion is experimentally demonstrated at a single photon power-level using an integrated Silicon ring resonator. This approach allows conversion of a photon to arbitrary wavelengths with no energy or phase matching constraints.

Time Shared Optical Network (TSON): a novel metro architecture for flexible multi-granular services [PDF]
, 2011 This paper presents the Time Shared Optical Network (TSON) as metro mesh network architecture for guaranteed, statistically-multiplexed services. TSON proposes a flexible and tunable time-wavelength assignment along with one-way tree-based reservation ...

Wavelength mutations and posttranslational autoxidation of green fluorescent protein.
Proceedings of the National Academy of Sciences of the United States of America, 1994 The green fluorescent protein (GFP) of the jellyfish Aequorea victoria is an unusual protein with strong visible absorbance and fluorescence from a p-hydroxybenzylidene-imidazolidinone chromophore, which is generated by cyclization and oxidation of the ...

WAVELENGTH DISCRIMINATION IN BLINDSIGHT
Brain, 1992 In the circumscribed, long-standing, clinically absolute visual field defects of three patients with vascular lesions that involved the optic radiation and visual cortex, forced-choice discrimination between coloured stimuli was tested. Paired stimuli were matched for luminous efficiency on the basis of previous measurements of increment-threshold ...

Comets at radio wavelengths [PDF]
Comptes Rendus. Physique, 2016 Comets are considered as the most primitive objects in the Solar System. Their composition provides information on the composition of the primitive solar nebula, 4.6 Gyr ago. The radio domain is a privileged tool to study the composition of cometary ices.

Research on the Displacement Sensing Structure with Varied Line-space Grating and Its Error Analysis
Guangtongxin yanjiu, 2021 Due to the low measurement precision, small measurement range and low stability of traditional displacement sensors, this paper propose and implement a displacement sensor based on varied line-space grating, with the displacement characteristic test and ...
