ABSTRACT All-optical xor operation has been demonstrated using a semiconductor optical amplifier Mach-Zehnder interferometer (SOA-MZI) and delayed interferometer (DI) at 80 Gb/s. The DI is based on a polarization maintaining loop (PML) mirror. The results show using the PML-DI in series with the SOA-MZI improves the pulse quality of the xor result

    • "Recently, the development of ultra high-speed Boolean logic gates [3] [4] [5] (such as AND, OR and XOR) with operating data rates higher than 40 Gbit/s have become the key enabling technology for realizing all-optical packet routing. At present packet header processing is carried out by sequentially correlating the incoming packet header address with each entry of a local routing table. "

    ABSTRACT: In this paper we present the modeling and simulation of multiple-hop routing in ultrafast all-optical packet switching based routers employing multiple pulse position modulation (PPM) formatted routing table. In multiple PPM routing tables (PPRTs) with reduced entry length, only a subset of the header address is converted into a PPM format in order to reduce the packet header recognition time. Packet header address correlation is carried out using only a single optical AND gate to improve the processing time. We show that the proposed scheme offers unicast/multi-cast/broadcast transmitting capabilities. The simulation results for the optical signal-to-noise ratio (OSNR) at each hop are presented and compared with the theoretical calculations.

    • "However, to fully utilize the potential of such networks, packet header processing and routing decision should be carried out in the optical domain rather than in the electrical domain to avoid the speed bottleneck imposed by the slow response of currently available electronic devices. Recently developed ultra high-speed Boolean logic gates (such as AND, OR and XOR) operating above 40 Gb/s have become the key enabling technology for realising all-optical routers [3] [4] [5]. At present, packet header recognition is carried out by sequentially correlating the incoming packet header address with every entry of a local routing table. "

    ABSTRACT: This paper presents an all-optical 1 x M WDM router architecture for packet routing at multiple wavelengths simultaneously, with no wavelength conversion modules. The packet header address adopted is based on the pulse position modulation (PPM) format, thus enabling the use of only a single- bitwise optical AND gate for fast header address correlation. It offers multicast as well as broadcast capabilities. It is shown that a high speed packet routing at 160 Gb/s can be achieved with a low channel crosstalk (CXT) of ~ -27 dB at a channel spacing of greater than 0.4 THz and a demultiplexer bandwidth of 500 GHz.

    ABSTRACT: In this paper, we propose an all-optical packet switched router using new packet header address correlation scheme based on with pulse position modulation (PPM) signaling format. Both packet header address and all the routing table entries are represented in PPM-format address and multiple pulse-position routing tables (PPRT) for considerably reducing the header recognition time. Multiple PPRTs not only downsize the routing table, but also offer the robust header recognition using a single optical AND operation. The paper presents the modeling of the router based on the proposed multiple PPRTs and the simulation verification.
