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...

Quantum coherence induces pulse shape modification in a semiconductor optical amplifier at room temperature

Coherence in light-matter interaction is a necessary ingredient if light is used to control the quantum state of a material system. Coherent effects are firmly associated with isolated systems kept at low temperature. The exceedingly fast dephasing in condensed matter environments, in particular at elevated temperatures, may well erase all coherent information in the material at timescales shor...

Semiconductor-Optical-Amplifier Mach-Zehnder Interferometer Based Optical Networks

In this paper, an all-optical AND logic scheme which exploits the cross-phase modulation (XPM) effect in semiconductor-optical-amplifier-assisted Mach-Zehnder Interferometer (SOA-MZI), is proposed, performance analyzed and parameters optimized. The proposal is validated and the system performance under various parameters is examined through numerical simulations. With only moderate parameters, ...

Exactly Solvable Model for Nonlinear Pulse Propagation in Optical Fibers

The nonlinear Schrödinger (NLS) equation is a fundamental model for the nonlinear propagation of light pulses in optical fibers. We consider an integrable generalization of the NLS equation which was first derived by means of bi-Hamiltonian methods in [A. S. Fokas, Phys. D 87 (1995), 145–150]. The purpose of the present paper is threefold: (a) We show how this generalized NLS equation arises as...
