We use the frequency-resolved optical gating (FROG) technique to determine the pulsewidth and chirp characteristics of wavelength-converted pulses from a turbo-switch and asymmetrical Mach-Zehnder filter combination under a variety of operating condi

We describe recent advances in the use of semiconductor optical amplifiers for all-optical signal processing of phase-based modulation formats. Four-wave mixing, which is inherently phase sensitive, is exploited in the techniques described.

It is shown that interferometers containing quantum-dot semiconductor optical amplifiers can be effective for ultrafast cross-phase modulation and digital signal processing with low dependence on the specific random data pattern.

Dynamic phase and amplitude all-optical responses of silicon nanowires are characterized using a terahertz optical asymmetric demultiplexer (TOAD) based pump-probe scheme. Ultra-fast recovery is observed for moderate pump powers.

We argue that the use of nonlinear semiconductor optical amplifiers for all-optical processing of phase encoded signals offers potential benefits. To illustrate the point, we demonstrate QPSK to 8PSK conversion and decomposition of QPSK to two BPSK o

All-optical processing of phase encoded signals with nonlinear semiconductor optical amplifiers offers potential advantages. As examples, we demonstrate QPSK to 8PSK conversion and decomposition of QPSK to two BPSK outputs at new wavelengths.

For the first time we demonstrate simultaneous suppression of phase distortion on two independent 10.7 Gbit/s DPSK modulated signal wavelengths using semiconductor optical amplifiers, realizing a compact phase sensitive amplifier with low power consu

We experimentally demonstrate 80 Gbit/s wavelength conversion to two copies by simultaneously extracting the blue- and red-shifted sidebands from XPM in a silicon nanowire. Bit error rates of 10-9 with only ~2 dB power penalty is achieved for both si
