The study of low-temperature photoluminescence spectra of Ga47In53As as a function of excitation intensity reveals three distinct features: With decreasing excitation intensity the excitonic lin

It has been known that complete elimination of one of the sidebands in FM can be achieved by modulating the envelope by a signal related to the baseband modulation.

Multiple spot beam communication satellites offer the potential for greatly increasing the traffic handling capability relative to wide-area coverage systems, since the allocated spectral band can

Picosecond pulses are observed to exhibit large frequency shifts (-50 GHz) and spectral distortion on propagation through semiconductor laser optical amplifiers.

Spectral hole burning experiments based on high-resolution magneto-CW four-wave mixing in the phase conjugate geometry show that both the spectral and spatial diffusion of excitons is negligible in

A spectral-phase encoded OCDMA system is demonstrated in a back-to-back optic fiber link.

Until now static spectrum management has ensured that DSL lines in the same cable are spectrally compatible under worst-case crosstalk conditions.

We report on the generation and the transmission of 1-Tb/s superchannels for long-haul optical systems.

We discuss the generation, wavelength-division-multiplexed (WDM) long-haul transmission, and coherent detection of 112- Gb/s polarization-division-multiplexed (PDM) 16-ary quadrature amplitude modu
