Operational Design on High-Speed Semiconductor Optical Amplifier With Assist Light for Application to Wavelength Converters Using Cross-Phase Modulation

We propose a new and potentially integrable scheme for the realization of an all-optical binary full adder employing two XOR gates, two AND gates, and one OR gate. The XOR gate is realized using a Mach-Zehnder interferometer (MZI) based on a semiconductor optical amplifier (SOA). The AND and OR gates are based on the nonlinear properties of a semiconductor optical amplifier. The proposed scheme is driven by two input data streams and a carry bit from the previous less-significant bit order position. In our proposed design, we achieve extinction ratios for Sum and Carry output signals of 10 dB and 12 dB respectively. Successful operation of the system is demonstrated at 10 Gb/s with return-to-zero modulated signals.

“…Many studies have paid more attention on SOA performance for implementing and configuring wavelength conversion sub-systems. Hence, several optical wavelength converters based on SOA nonlinearities have been proposed and discussed, such as XGM (Tzanakaki & O'Mahony, 2000), XPM (Matsumoto et al, 2006), FWM (Contestabile et al, 2004), and XPolM (Wei et al, 2005). Each configuration has its advantages and disadvantages and thus its framework of application in optical communication networks.…”

Abstract-Nonlinearity effects, arising within a semiconductor optical amplifier, have been deeply investigated with particular interest for exploiting them in wavelength conversion. This application shrinks the research area to a precise scenario: a strong pump signal travels through the active medium simultaneously with a modulated signal to be converted. In this case it is possible to neglect the spectral distribution of the optical power and phase relationship between propagating signals. SOAs have been also studied as line amplifiers for WDM phase modulated signals. Aim of this paper is to extend the propagation model in a SOA, in order to simulate nonlinearities occurring in the amplification of a WDM comb signal evaluating FWM on constant envelope modulation schemes (DPSK). This can be carried out thanks to an enanched analytical model based on the optical field and medium interaction, overcoming the wide-used Rate Equation approach, which is based on the overall photons density.
