Noise suppression using optimum filtering of OCs generated by a multiport encoder/decoder

We propose a novel receiver configuration using an extreme narrow band-optical band pass filter (ENB-OBPF) to reduce the multiple access interference (MAI) and beat noises in an optical code division multiplexing (OCDM) transmission. We numerically and experimentally demonstrate an enhancement of the code detectability, that allows us to increase the number of users in a passive optical network (PON) from 4 to 8 without any forward error correction (FEC)

One-way reservation scheme using optical code processing for fast data transfer

Abstract OBS (Optical Burst Switching), in which wavelengths are reserved on a demand basis is one way to effectively use WDM networks. To reduce overhead time, high-speed processing of the signaling message at each hop is imperative. However, conventional electronic processing is not fast enough and will eventually become a bottleneck as the bit rate of data links increase. To reduce the overhead time in OBS networks, we propose an OC-TAG (Optical Code based Tell-And-Go) protocol for transmitting variable length burst without buffering, and fast burst transfers over WDM networks. Optical-code-based processing is introduced for handling the out-of-band control packets. Through computer simulation, we show the effect of introducing our protocol
