Despite recent progress in nonlinear optics wavelength-scale resonators, there are still open questions on the possibility of parametric oscillation such resonators. We present a general approach to predict behavior and estimate threshold multi-mode subwavelength optical oscillators (OPOs). As an example, we propose OPO based Mie-type multipolar resonances, demonstrate that due low-Q nature mod...

Our study examined the impact of daylight (photophase) wavelength on the photoentrainment sensitivity of two species with vastly different visual systems. Social voles (Microtus socialis) and 'blind' mole rats (Spalax ehrenbergi) were exposed to short-wavelength (479 nm) or long-wavelength (697 nm) light at an intensity of 293 μW cm(-2). Rhythms of urine production, urinary 6-sulfatoxymelatonin...

This study aims at highlighting the Routing and Wavelength Assignment (RWA) problems in WDM Optical networks and describes the Routing Algorithms and their performance comparison. Since routing decisions play an important role in evaluating the blocking performance of a network it is critical to choose a wavelength assignment scheme that should take into account its compatibility with the chose...
