The impulse regenerator has been used to eliminate distortions which have arisen as the result of line and exchange conditions.
We analyze the experimental impulse response of coupled-core 3-core fibers and compare the results against super-mode calculations.
Although single-mode operation of clad optical fibers is possible and, in general, offers very good transmission characteristics, multimode fibers have two advantages: They impose less stringent re
Multimode operation of optical fibers relaxes the fabrication tolerances, allows the use of incoherent sources, and can alleviate handling and splicing problems.
We report on the impulsive excitation and control of intersubband and hybrid intersubband-cyclotron modes in a two-dimensional electron gas by ultrafast optical pulses.
Silicon tetrafluoride, SiF(4), of high purity with respect to either hydrogen- or oxygen-containing species is required by the optical waveguide telecommunications and photovoltaic industries, res
Amorphous Si has been formed from the melt by the UV laser heating of surface layers of single crystal (111) Si.
The results of transport measurements on p-type CuInSe2 single crystals in the temperature range of 20 to 300 K are presented and explained assuming the existence of an impurity band.
Using several deriatives of scanning force microscopy with conducting tips, we find direct evidence for impurity band conduction in GaN films near the sapphire substrate interface.
The platinum-impurity diffusion in icosahedral Al(86)Mn(14) produced by melt-spinning has been measured for the first time.
