A grating-based OCDMA coding:decoding system incorporating a nonlinear optical loop mirror for improved code recognition and noise reduction

, 2002
We demonstrate an elementary grating-based optical code division multiple access (OCDMA) code generation and recognition system incorporating a nonlinear optical loop mirror (NOLM) within the receiver.

All-optical TDM data demultiplexing at 80 Gbit/s with significant timing jitter tolerance using a fiber Bragg grating based rectangular pulse switching technology

, 2003
We demonstrate the use of fiber Bragg grating based pulse-shaping technology to provide timing jitter tolerant data demultiplexing in an 80 Gb/s all-optical time division multiplexing (OTDM) system. Error-free demultiplexing operation is achieved with ~6

Self-switching with a nonlinear birefringent loop mirror

, 2000
We investigate switching characteristics of the nonlinear birefringent loop mirror which consists of a symmetric directional coupler, a birefringent fiber, and a symmetry-breaking element that converts linearly polarized light to circularly polarized ...

Microstructured optical fibres for gas sensing: design fabrication and post-fab processing

, 2009
Air/silica Microstructured Optical Fibers (MOFs) offer new prospects for fiber based sensor devices. In this paper, two topics of particular significance for gas sensing using air guiding Photonic Bandgap Fibers (PBGFs) are discussed.
