All-optical wavelength converter scheme for high speed RZ signal formats

Abstract-Semiconductor optical amplifiers are useful building blocks for all-optical gates as wavelength converters and OTDM demultiplexers. This paper reviews the progress from simple gates using cross-gain modulation and four-wave mixing to the integrated interferometric gates using cross-phase modulation. These gates are very efficient for high-speed signal processing and will open up interesting new areas, such as all-optical regeneration and high-speed all-optical logic functions.Index Terms-Add/drop multiplexer, optical gate, optical processing, semiconductor optical amplifier, wavelength converter.

“…Aided by the simulator, an optimization procedure of the AMZI structure and the operational parameters to carry out all-optical wavelength conversion (WC) can efficiently be achieved. For WC to occur (Mikkelsen et al 1997), a data signal (here a 40 Gb/s PRBS with 8.25 ps Gaussian pulses) and a CW beam at the target wavelength are injected into the AMZI. See Figs.…”

A versatile modular computational tool for complex optoelectronic integrated circuits simulation r a mó n g u t ié r r e z -c as t r e jó n 1, * , m a r c u s d u e l k 2 and p i e t r o b e r n a s c o n i 2 Abstract. A novel graphical computational tool to simulate a wide variety of complex optoelectronic integrated circuits is presented. Based upon a modular approach, this tool reduces the optical circuit into a sequence of interconnected building blocks, each one performing a specific data-flow oriented function onto an input optical stream. The modularity and the flow-based interconnectivity makes this simulator flexible and powerful, yet intuitive. Its execution speed is evaluated using a sophisticated amplifier simulation module that is compared against its replica written in a text-based programming language. More than four times outperformance is reported. The simulator capabilities are further demonstrated through an application example in the field of optical data processing: the analysis of a semiconductor optical amplifier-based Mach-Zehnder interferometer operated as wavelength converter for signals modulated at 40 Gb/s. This simulator represents an attractive alternative to more traditional approaches.

Abstract:We analyze signal waveform generated by a semiconductor optical amplifier (SOA)-based switch with a delayed-interferometric (DI) configuration by controlling an assist light under gain or transparent wavelength. To take advantage of the rectangular-shape waveform generated by the switch, we investigate and optimize the waveform quality by means of both Q-factor and concordance rate to rectangularshape of the converted waveform.
