Sub-picosecond all-optical switch using a multi-quantum-well semiconductor optical amplifier
We investigate an all-optical switch that is operated by the nonlinear phase-shift introduced by optical pulses with duration of 200 fs in a semiconductor optical amplifier (SOAs). The gate is made out of a commercially available InGaAsP–InGaAs multi-quantum-well (MQW) SOA placed in a Mach–Zehnder interferometer. We have measured the nonlinear phase-shift as a function of the injection current ...
متن کاملAll-optical measurement of nuclear-spin relaxation
Nuclear-spin relaxation rates are usually measured by pulsed radio frequency excitation of nuclear-spin transitions. When the number of spins is too small for direct detection with conventional nuclear-magneticresonance spectrometers, pulsed excitation may be combined with optical detection of the nuclear spins for increased sensitivity. Here we demonstrate that such measurements can also be do...
متن کاملThe Effects of Strained Multiple Quantum Well on the Chirped DFB-SOA All Optical Flip-Flop
In this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (MQW) chirped distributed feedback semiconductor optical amplifier (DFB-SOA) all-optical flip-flop is precisely derived. We have analyzed the effects of strains of QW and MQW and cross phase modulation (XPM) on the dynamic response, and rise and fall times of the ...
متن کاملPicosecond all-optical switching in hydrogenated amorphous silicon microring resonators.
We utilize cross-phase modulation to observe all-optical switching in microring resonators fabricated with hydrogenated amorphous silicon (a-Si:H). Using 2.7-ps pulses from a mode-locked fiber laser in the telecom C-band, we observe optical switching of a cw telecom-band probe with full-width at half-maximum switching times of 14.8 ps, using approximately 720 fJ of energy deposited in the micro...
متن کاملAll-Optical Switching of Picosecond Pulses by Four-Wave Mixing in a Semiconductor Optical Amplifier
High-speed all-optical switching is demonstrated by four-wave mixing (FWM) of picosecond pulses using semiconductor optical amplifiers (SOA). A light source for measurement and switching in the 1.5 μm region is produced using a normal group velocity dispersion fiber and optical parametric oscillator. The output supercontinuum (SC) optical pulses, with a spectral width of approximately 300 nm, a...
