“…It is important to note that the drawbacks of contra-propagation set-up (longer fall time, pulses overlapping at different places inside the SOA depending on the delay) are not relevant here as the proposed model will take them into account, allowing an estimate of ε comparable to that achieved in a co-propagation set-up. A schematic and a full description of the set-up can be found in [6]. It is a one color pump probe contrapropagation set-up with a full control of the state of polarization of the pump and probe signals injected.…”

Abstract:We investigate the power and the polarization dependence of the intraband dynamics in a bulk semiconductor optical amplifier using both a 2.5-ps pump-probe experimental set-up in contra-propagation and a theoretical model. Our model is based on the rate equations and takes into account the polarization dependence of the gain. By comparing experimental and computational results we are able to highlight the dependences of the intraband dynamics and to extract the non-linear gain compression factor as a function of both pulse energy and polarization of the injected pulses.

“…It has proven to be a versatile and multifunctional device to be used to achieve different functions in access, core, and metropolitan networks. Particularly, it has been envisioned for all-optical signal processing tasks at very high bit rates, that cannot be handled by electronics, such as wavelength conversion [1][2][3][4], signal regeneration [5,6], optical switching [7] and, optical logic operations [8][9][10].…”

We highlight the feasibility of experimental implementation of both inverted and noninverted wavelength conversion, 2R regeneration, and all-optical logic functions, such as OR, NOR, XOR, and XNOR optical gates by exploiting the self-polarization rotation in a semiconductor optical amplifier (SOA) device without changing the setup configuration. Switching between each optical function is done by only adjusting the input optical power level. In order to allow optimum control and preserve the polarization state of the injected and collected signals, the polarimetric measures have been carried out in free space.

This article overviews the fundamental principles and attributes of the major all‐optical signal wavelength conversion (AOWC) methods commonly found in the literature over the last 25 years from the system perspective, which are oriented mainly for telecommunications applications. Two principal AOWC categories are analyzed: first, the optically controlled gates based on semiconductor optical amplifiers (SOAs) or electroabsorption modulators (EAMs) and second, the wave‐mixing AOWC schemes exploiting χ (3) or χ (2) material nonlinearities. In the case of the SOA‐based gates, the effects of cross gain modulation (XGM) and cross phase modulation (XPM) – with or without the employment of the offset filtering technique – are explained and a brief description of the regenerative schemes with SOA‐MZI (Mach‐Zehnder interferometer) switches is attempted. For the case of EAM‐based gates, both XAM and XPM effects are mentioned, utilized for efficient AOWC of intensity‐modulated signals. The wave‐mixing methods, covered in Section 2 of the article, start with the four wave mixing (FWM) effect on χ (3) materials, describing methods to implement polarization insensitive operation. Special attention on the AOWC of advanced modulation formats is attempted by explaining methods on minimizing the phase noise induced on the conversion process. For AOWC on χ (2) , materials the fundamental effects of difference frequency generation (DFG), sum frequency generation (SFG), and sum harmonic generation (SHG) are explained. In addition, particular focus is put on the attributes and the wavelength mapping of the cascaded cSFG/DFG and cSHG/DFG processes utilized in most AOWC‐schemes based on χ (2) nonlinearities.
