“…The incurred extra power penalty is less than 0.5 dB from 40 Gb/s RZ UWC to 1 × 2 40 Gb/s RZ MWC. Compared with the power penalties of 8 dB and 10 dB for inverted and non-inverted 2 × 40 Gb/s RZ AOWC in [12], respectively, the presented wavelength converter in this paper has a relatively improved performance. One reason is the longer active length and larger biased current of SOA can speed up the slow gain recovery.…”

“…However, SOA-based wavelength conversion presents several drawbacks due to the slow carrier recovery time of the SOA which limits the operation speed, the resulting inverse polarity of the converted signal, and the poor extinction ratio (ER) [10]. To overcome these issues, different integrated schemes have been proposed by exploiting fully integrated SOA delayed-interferometer (DI) configuration [11], monolithically integrated SOA assisted by a blue-shifted filter [12], and double-stage SOAs [13]. Most schemes were used to demonstrate operation for return-to-zero (RZ) or non-return-to-zero (NRZ) signals only.…”

Abstract: We present an InP monolithically integrated all-optical wavelength converter array chip and experimentally validate its performance for unicast (single output wavelength) and multicast (multiple output wavelengths) wavelength conversion. The monolithically integrated chip includes four semiconductor optical amplifiers with an arrayed-waveguide grating and two delayed interferometers. The chip is fabricated on a multi-project wafer (MPW) platform, which allows multiple designers to share space on the same wafer exploiting a generic integration platform. We demonstrate error-free non-return-to-zero (NRZ) unicast wavelength conversions using 2 31-1 pseudorandom bit sequence data at 10 Gb/s, 20 Gb/s and 40 Gb/s with a 25-nm conversion range. Power penalties as low as 2.3 dB and 2.7 dB for NRZ and return-to-zero (RZ) unicast wavelength conversion at 40 Gb/s are obtained, respectively. Additionally, power penalties of 2.5 dB for NRZ and 3.2 dB for RZ signals at 40 Gb/s 1 × 2 multicast wavelength conversions are also achieved. conversion by semiconductor optical amplifiers," J.

“…Table 2 summarizes the results of experiments/simulations that employed SOA-based optical switches assisted by optical filtering. [4][5][6][7][8][9][10] Wavelength conversion has been demonstrated for bit rates up to 320 Gb∕s. Since the polarity of wavelengthconverted return-to-zero (RZ) signal is inverted by XGM, notch filters that suppress the DC component were used after BPFs to obtain non-inverted data signals.…”

Abstract. Increasing communication traffic and plans to increase various services may cause a serious problem towards the power consumption of network equipment. One of the causes of large power consumption in the present network is the multiplexing scheme, such as wavelength division multiplexing (WDM) and electrical routing of the packet signals. WDM requires O/E (optical to electrical) and E/O (electrical to optical) signal conversion circuits with the same number as that of wavelength, resulting in an increase in power consumption. In addition to this electrical signal processing for the IP packet, routing, and switching at the router consumes a large amount of power. If we could process ultrafast signals using electromagnetic light waves without converting to electrical signals, this would reduce the power consumption of routers. One of the ways to overcome these problems is the development of all-optical computing devices. All-optical computing devices are based on the nonlinear interaction of light waves, which is an electromagnetic wave. The use of electromagnetic light waves makes computing, such as switching, possible at very high frequencies of more than 100 GHz. We discuss all-optical computing devices based on semiconductor optical amplifiers with the main emphasis on all-optical logic gates.

“…The routing signal at unique wavelength has a time duration equal to the packet time. The wavelength of the routing signal represents the central wavelength at which the 160 Gb/s data payload will be converted by means of wavelength conversion [15,16]. Simultaneously, the label rewriter, which is based on the same operation principle of the label processor, provides the new labels, which have a time duration equal to the packet duration.…”

Abstract-In this paper two different paradigms to realize a scalable all-optical packet switch with label swapping will be presented. All the functions required for switching the packets are based on all-optical signal processing without any electronic control. This allows very low latency and potential photonic integration of the systems. We report for both techniques experimental results showing the routing operation of the 160 Gb/s packets and beyond. We will discuss and compare both techniques in term of devices and bit-rate scalability, latency, power consumption, power penalty performance and cascadability as key parameters for the realization of an all-optical packet switch.Index Terms-Optical packet switching, optical signal processing, label processor, label rewriter, label swapping, semiconductor optical amplifier.
