One reason is that true blue colours or pigments simply don't exist in nature, and plants and animals have to perform tricks to appear blue, according to the University of Adelaide. Take blue jays for ...

Abstract: In optical time-wavelength interleaving signal generation systems, amplitude and time delay mismatch between channels can significantly degrade the quality of the output signals. To mitigate ...

Abstract: We propose a novel inter-band wavelength conversion strategy for multi-band optical networks with a partial set of band-upgraded links. Simulation results demonstrate that the proposed ...
