Simulation of polarimetric radar variables in rain at S-, C- and

Abstract-We experimentally demonstrate a wide-band wavelength converter enabled by continuous-wave (CW) triggered supercontinuum (SC) generated from a picosecond pulse source. In the presence of the trigger, the pulse-to-pulse SC stability considerably improved, leading to error-free wavelength

Abstract—A simple ring laser technique of two-stage gain-clamped long-wavelength band erbium-doped fiber am-plifier is investigated. The ring laser light is excluded at the output end and noise-figure degradation can be reduced due to the counterpropagating partial gain-clamping in the second stage

that shows a strong correlation with reflectance within its particular band of wavelengths. These images are not mixed, but rather are compared to generate color sensations. The problem then becomes how the lightness of areas in these separate images can be independen t of flux. This article describes

We report on the operation of a novel laser system delivering high-energy pulses in the near-infrared region. The pulses are nearly Fourier-transform limited ͑time-bandwidth product of 0.48͒, providing narrow-band radiation (ϳ1.5 GHz), with an energy of 225 mJ and 10 Hz repetition rate. The pulse

Abstract—Wavelength up-conversion of 1.6-ps pulses is achieved through four-wave mixing (FWM) in an InAs–InP quantum-dash ridge waveguide laser operating at 1587 nm. The up-conversion efficiency is measured as a function of injection current, for pump–probe detunings in the range 1.8–3.8 THz

A novel type of hybrid amplifier/wavelength converter is presented, coupling a TDFA and a FOPA module in series. Signal amplification over the entire S-Band (1450-1530 nm) and signal-to-idler conversion from 1540-1630 nm is demonstrated.

With a conventional lens sharpness of the image is always limited by the wavelength of light. An unconventional alternative to a lens, a slab of negative refractive index material, has the power to focus all Fourier components of a 2D image, even those that do not propagate in a radiative manner
