All-optical wavelength conversion plays a major role in providing the wavelength flexibility in optical communication networks. All-optical wavelength converters (AOWCs) based on cross-gain modulation (XGM) and cross-phase modulation (XPM) in semiconductor optical amplifiers (SOAs) have attracted considerable research interest. In this paper, we propose a novel scheme for cascaded wavelength conversion based on cross-gain modulation and cross-phase modulation in SOAs. The wavelength conversion operation in the proposed scheme includes two stages, that is, XGM in the first stage followed by the stage of XPM, and thus is expected to have a high ER and a large input power dynamic range simultaneously.

We analyze the performance of a new all-optical label swapping (AOLS) router based on two-stage wavelength conversion and verify that the scheme can offer excellent performance over about 10 dB power dynamic range and over a wide range of operation currents. IntroductionDense-wavelength-division-multiplexing (DWDM) transmission and all-optical switch/routers (AOSR) are considered the critical technologies for the next-generation all-optical network. All-optical label swapping (AOLS) technology has been proposed to realize AOSRs [1]. For AOLS, the low-speed label associated with a high-speed payload is extracted, processed, and replaced at every intermediate network-switching node. The high-speed payload is optically switched in terms of the electrically processed label to a designated output wavelength. Wavelength conversion technology is frequently used in an AOSR such that it is transparent to the payload data rates. Many AOLS techniques have been proposed, including the time-domain-multiplexing technique, subcarriermultiplexed labeling technique, orthogonal modulation technique [2]. It was proposed that the label and payload can be processed by adding a low-speed ASK label on top of a high-speed ASK payload. Such an ASK labeling technique requires only low-speed external modulators and low-speed optical receivers to perform the label swapping function. However, this approach requires complicated signal processing and compromise between the performance of header and that of payload.In this paper, we will investigate a new approach for AOLS and analyze its performance by using VPIcomponentMaker Active Photonics version6.0 simulation tool. Fig.1 is the proposed AOLS switching architecture [3]. The incoming label and payload signals are carried by two closely-spaced wavelength channels. They can be separated by a de-interleaver of which the channel spacing is 50GHz in the paper. The channel spacing can be smaller to enhance channel efficiency. The incoming label is electronically processed to generate a new label and to create a control signal. The new label is sent to directly modulate a fixed-wavelength laser, so that a new optical label will be generated. The payload is wavelength converted to the adjacent channel of the above fixed-wavelength laser. A wide-band wavelength converter (WC) is used to switch the label/payload to new wavelength positions by using a tunable laser as the pump. The output wavelengths of the label and payload can be simultaneously routed to its designated path with a wavelength router. Dual-pumped four-wave mixing mechanism in a SOA is proposed to provide the wideband WC [4]. Thus, the payload is optically processed by two-stage WCs in an AOLS router. In this paper, we investigate the signal characteristics and system performance of the router. The data rate is 10Gb/s. The effects of extinction ratio (ER), operation currents, attenuation, and power control on the router performance will be reported.
