The spectral efficiencies of optical modulation and detection schemes are computed using information-theoretic techniques.

Several optical modulation and detection schemes are compared by computing their spectral efficiencies over a simple channel model.

Several optical modulation and detection schemes are compared by computing their spectral efficiencies over additive white Gaussian noise channels.

In recent years, the ever growing need for higher capacity in wireless systems has fueled the,interest in exploiting the spatial dimension-through the use of antennas rrays-to improve the utilizati

The use of multiple antennas at the transmitter and the receiver is considered for the uplink of cellular communication systems.

Recent information-theory results have shown the enormous capacity potential of wireless techniques that use transmit and receive antenna arrays.

We investigate the potential of spectral engineering to mitigate the penalties on 32-Gbaud 256-Gb/s PDM-16QAM channels passing through the deployed cascade of 37.5-GHz wide filters in case of wavel

The implications of filtering the emission from a quantum-dash Fabry-Perot laser, which is actively mode locked by injection of a 40 Gb/s return-to-zero on-off-keyed signal, are investigated in the

Using an effective Hamiltonian which takes into account the constraints on the motion of a hole in a quantum antiferromagnet (QAFM), the spectral function of the hole is calculated.

The nonlinear susceptibility of semiconductor gain media is obtained by including the effect of intraband carrier relaxation within the density-matrix formalism.
