All-optical wavelength conversion based on the Linear Optical Amplifier (LOA) is demonstrated for the first time.

Present performance of cellular systems is restricted by the method used to combine signals before they are transmitted from the cell site.

The effect of prior knowledge when linear analog codes are used as joint source-channel codes for sources modeled as multivariate Gaussian processes is analyzed.

We review the unique resistance of coherent systems to linear effects and the challenges to digitally mitigate nonlinearities.

The operational characteristics of a time-to-space processor based on three-wave mixing for instantaneous imaging of ultrafast waveforms are investigated.

We experimentally examine the performance of a single-polarization 42.7-Gb/s RZ-DQPSK optical signal.

In the G.fast frequency range (up to 212 MHz), the diagonal dominance structure of the channel matrix is no longer valid at higher tones.

We report on first optical measurements of semiconductor nanocrystals incorporated into fluorinated polymer nased waveguides.

Semiconductor Optical Amplifiers (SOAs) may be designed as linear or nonlinear network elements.

Two selected applications of semiconductor optical amplifiers (SOA) are discussed, namely linear in-line amplification in gigabit passive optical networks and fast nonlinear all-optical signal proc
