“…Previous implementations of single-pulse extraction techniques involve a marker pulse at the beginning of the packet at a different state relative to the rest of the packet in terms of either wavelength [18], polarization [19], bit period [20], or amplitude [21], resulting in increased complexity to the generation and transmission of packets. More recently, experiments have been reported where all the pulses of the packet share the same physical state [22], [23].…”

“…The first step of the operation is header recognition and serial to parallel conversion of the header bits. Various techniques might be applied for these operations [6][7][8]. Every serial-to-parallel converted bit is sent to the pulse extension module, which extends the pulses in time up to the duration of the whole addresses in the routing table.…”

Increasing bandwidth demand, mostly driven by the Internet Protocol (IP), has made researchers consider to deploy all-optical devices into packet switched networks. Despite huge bandwidth of the optical communication links (optical fiber) the usable capacity is limited due to bottlenecks (congestions) at the switching nodes. In this paper, a novel all-optical routing architecture is proposed for optical packet switched networks. In the design, practical optical devices (gratings, threshold elements, optical delays, and couplers) have been improved and exploited in order to integrate into an alloptical routing device. The system has been implemented and simulated by using an photonics simulation package (VPI-Virtual Photonics). The packets conveying a three-bit routing information tag at the bit rate of 10 Gbps have been successfully routed between two links. Some of the components are standard tools of the simulation package and some needed to be designed using the transfer function or theory developed in the literature. Noise and losses associated to the nonideal nature of the components are considered in the simulation as well.

“…The dual-rail XOR logic gate is also of paramount importance because it allows the full complement of Boolean bitwise logic to be performed on ultrafast optical signals. XOR gates can be used to implementcomplexopticalprocessingcircuitslikeaddressrecognition schemes [48]- [52], data encoders/decoders, or optical decision circuits [8].…”

Abstract-In this paper, we review recent advances in ultrafast optical time-domain technology with emphasis on the use in optical packet switching. In this respect, several key building blocks, including high-rate laser sources applicable to any time-division-multiplexing (TDM) application, optical logic circuits for bitwise processing, and clock-recovery circuits for timing synchronization with both synchronous and asynchronous data traffic, are described in detail. The circuits take advantage of the ultrafast nonlinear transfer function of semiconductor-based devices to operate successfully at rates beyond 10 Gb/s. We also demonstrate two more complex circuits-a header extraction unit and an exchange-bypass switch-operating at 10 Gb/s. These two units are key blocks for any general-purpose packet routing/switching application. Finally, we discuss the system perspective of all these modules and propose their possible incorporation in a packet switch architecture to provide low-level but high-speed functionalities. The goal is to perform as many operations as possible in the optical domain to increase node throughput and to alleviate the network from unwanted and expensive optical-electrical-optical conversions.Index Terms-Exchange-bypass switch, interferometric gates, optical switching, optical time-division multiplexing (OTDM), packet switching, optical signal processing, semiconductor optical amplifier (SOA).
