We have observed evidence for the correlation-induced Coulomb gap in the density of hole states (DOS) in a lightly-doped, compensated (K~0.5) GaAs.
Abstractâ"In this paper, we develop the most general first-order perturbation theory of the propagation of a signal in an optical fiber in the presence of amplification and Kerr nonlinearity, vali
Current optical fibre transmission systems rely on modulation, coding and multiplexing techniques which were originally developed for linear communication channels.
A planar lightwave circuit with a length-imbalanced Mach-Zehnder interferometer and an arrayed waveguide grating radiating into free-space generates nonlinearly spatially dispersed light.
New phenomena in which the stimulated Brillouin scattering (SBS) changes the number and magnitude of frequency shifts in a plasma upon a nonlinear increase in the pumping field intensity are discov
Intensity-dependent absorption, low-intensity pump-and-probe and forward-degenerate-four-wave-mixing experiments were performed in InGaAs/InP multiple -quantum-well structures, whose fundamental b
The first investigation of nonlinear absorption in InGaAs/InAlAs multiple quantum wells using picosecond and CW infrared lasers is presented.
The spin dynamics of Fermi liquids and dilute polarized gases can be reduced in the nonlinear limit to a dissipative Heisenberg ferromagnet model.
The ab-plane resistivity of YBa sub 2 Cu sub 4 O sub (8+-delta) (1:2:4) films is measured from 68K to 600K and found to be a nonlinear function of temperature in contrast to that of YBa sub 2 Cu su
We investigate the impact of tight filtering and WDM crosstalk on the performance of 100Gb/s coherent PDM-QPSK over a terrestrial transmission link.
