Optical Phase Conjugation Conversion through a Nonlinear Bidirectional Semiconductor Optical Amplifier Configuration

Efficient Optical Phase modalation using A Semiconductor Optical Amplifier

Effect of carrier depletion on optical phase conjugation in a semiconductor laser amplifier.

The temporal effect of optical phase conjugation in a semiconductor laser amplifier is studied numerically. The conjugate pulse has distortion and frequency chirping owing to the carrier depletion induced by the signal pulse. Both the pulse-shape distortion and frequency chirping are enhanced as the signal power and the injection current increase. We can reduce these two effects by increasing t...

All Optical Parametric Frequency Conversion Based on Cross Gain Modulation on a Reflective Semiconductor Optical Amplifier

This paper reports a detailed experimental study of the wavelength conversion dynamics using cross-gain modulation in reflective semiconductor optical amplifiers. The effect of pump and probe powers on the operating performance in terms of signal to noise ratio was experimentally investigating. The variation of others performance indicators such as extinction ratio, timing jitter and eye openin...

All-optical 1310 to 1550 nm wavelength conversion by utilising nonlinear polarisation rotation in semiconductor optical amplifier - Electronics Letters

Introduction: One of the key components in all-optical communication networks using the whole low-loss bandwidth of the silica fibre is an ultra-wideband wavelength converter [1]. Use of all-optical ultrawideband wavelength converters enhances network flexibility, allowing an all-optical wavelength conversion between different transmission windows, and therefore avoiding the bottleneck of optic...

Nonlinear polarization rotation induced by ultrashort optical pulses in a semiconductor optical amplifier

We use a new rate-equation model for the propagation of sub-picosecond polarized optical pulses in a semiconductor optical amplifier (SOA). This model is based on the decomposition of the polarized optical field into TE and TM components that interact via the gain saturation, and accounts for two-photon absorption, free-carrier absorption, selfand cross-phase modulation, carrier heating, and sp...
