We present an incoherent optical spectral CDMA (OS-CDMA) multiple-access system that uses in-fibre Bragg gratings for encoding/decoding. The system comprising four channels, one desired and operating at a 2.5Gbps and 10Gbps. Our measurements verify that this technique suffers from severe chromatic dispersion. Nevertheless with appropriate dispersion compensation, the system is able to achieve a span of 100km.
This paper presents a study on an all-optical multicasting switching matrix design based on SOA and AWG technology
for all optical DWDM network. The technique not only has the capability to control the degree multicasting optically but
also perform double stage of wavelength conversion. Experimental results have shown the design's capability to
multicast an incoming 10Gbps optical signal onto 16 outgoing signals using Cross Gain Modulation and then using
Cross phase modulation as a second stage of conversion to perform 2R (re-amplified and re-shape).
In this paper we present an initial result of a novel architecture of an all-optical buffer by re-circulating packets dynamically using Semiconductor Optical Amplifier (SOA) and Fiber Bragg Grating (FBG). We then compare this architecture with typical re-circulating buffer with respect to output power and the eye diagram. We start our work by investigating the performance of wavelength routed optical network using an Object Oriented Programming methodology (OOP). In particular, we examine wavelength routed switching matrix architecture employing Arrayed Waveguide Grating (AWG), multiplexer (MUX) and demultiplexer (DEMUX) and SOA. Parameters of interest are throughput and packet loss of different number of optical buffer used with different offered load.
This paper introduces a design for a high capacity multicasting capable Optical Packet Switched Router (OPSR). It incorporates an Arrayed Waveguide Grating (AWG) as its core switching matrix to manage the ever increasing packet switched traffic within the optical network. The OPSR has the capability to switch optical packet traffic through the AWG with a switching speed of a few nano-seconds (nsec) at a bit rate of 10Gbps and above with multicasting capability. The capabilities offered by this OPSR will speed up all-optical packet switching and reduce packet latency and consequently packet loss.
