Abstract-The objective of this research is to propose two new optical procedures for packet routing and forwarding in the framework of transparent optical networks. The single-wavelength label-recognition and packet-forwarding unit, which represents the central physical constituent of the switching node, is fully described in both cases. The first architecture is a hybrid opto-electronic structure relying on an optical serial-toparallel converter designed to slow down the label processing. The remaining switching operations are done electronically. The routing system remains transparent for the packet payloads. The second architecture is an all-optical architecture and is based on the implementation of all-optical decoding of the parallelized label. The packet-forwarding operations are done optically. The major subsystems required in both of the proposed architectures are described on the basis of nonlinear effects in semiconductor optical amplifiers. The experimental results are compatible with the integration of the whole architecture. Those subsystems are a 4-bit time-to-wavelength converter, a pulse extraction circuit, a an optical wavelength generator, a 3 8 all-optical decoder and a packet envelope detector.Index Terms-Optical header processing, optical logic gate, optical packet switching, semiconductor optical amplifier (SOA), transparent optical network.

“…A decoder is important for header processing in typical core router/demultiplexer for addressing output port. There are many research areas which have been proposed using various all-optical switching and all-optical logic operation, such as all-optical packet-switching [1], all-optical demultiplexing [2] semiconductor optical amplifier (SOA) [3]- [5], TOAD based interferometer device [6]- [9], cascaded microring resonators [10], and all-optical code conversion [11]- [13]. Among the different proposed schemes, the terahertz optical asymmetric demultiplexer (TOAD)/semiconductor optical amplifier (SOA)-assisted Sagnac gate effectively combines fast switching time and a reasonable noise figure, with the ease of integration and overall practicality that enables it to compete favorably with other similar optical time division multiplexing devices.…”

An all-optical 2-to-4 decoder unit with the assist of terahertz optical asymmetric demultiplexer (TOAD) is presented. The all-optical 2-to-4 decoder with a set of all-optical switches is designed which can be used to achieve a high-speed central processor unit using optical hardware. The unique output lines can be used for all-optical header processing. We attempt to develop an integrated all-optical circuit which can perform decoding of signal. This scheme is very simple and flexible for performing different logic operation and to design advanced complex logic. Simulated results are confirming the described methods.

“…Raman amplifiers, erbium-doped fiber amplifiers (EDFA) and hybrid amplifier (Raman/EDFA/SOA) have already been proposed as in-line amplifiers. Power consumption, size and cost of such amplifiers are normally higher than semiconductor optical amplifiers (SOAs), which offer an alternative solution [1,2]. The general drawbacks of this alternative technology are relatively high noise, susceptibility to electrostatic shock and gain saturation (caused by carrier depletion) resulting in reduced optical gain at high input powers and serious waveform distortion known as the patterning effect in SOAs.…”

A broadband semiconductor optical amplifier (SOA) has been realized for the coarse WDM (CWDM) based systems operating over the O-band range. The SOA exhibits low polarization sensitivity, 23 dB gain and low noise based on the asymmetric multi-quantum well (AMQW) technique. Reflective SOAs (for modulating the upstream data in passive optical networks (PONs)) as well as in-line or booster amplifiers in CWDM systems are some of the applications of such a SOA.
