The optical fibre Sagnac interferometer was first demonstrated over 25 years ago.
Immediately its potential for gyroscopic measurements became apparent and since the first …

This review is concerned with the physical problems of fiber ring interferometry which
underlies the fiber-optic gyroscopy harnessing the Sagnac effect. Locally reciprocal and …

We describe recent results of the Advanced Research Projects Agency (ARPA) sponsored
Consortium on Wideband All-Optical Networks which is developing architectures …

Ultrafast all-optical signal processing techniques are expected to play a major role in future
ultrafast single-carrier soliton systems, because they remove the electronics bottleneck. In …

We report what is to our knowledge the first clear-cut experimental evidence of the
reversibility of modulational instability in dispersive Kerr media. It was possible to perform …

We observe mixed two-and three-photon absorption in bulk rutile (TiO_2) around 800 nm
using the open aperture Z-scan technique. We fit the data with an extended model that …

This paper investigates experimentally and theoretically the signal-to-noise ratio (SNR)
characteristics of 100 Gb/s all-optical demultiplexing using a nonlinear optical loop mirror …

From the perspective of the differential phase delay experienced by the two
counterpropagating optical fields, the self-starting of the mode-locked fiber laser with a non …

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 …

A fiber loop mirror (FLM) filter with two-stage polarization-maintaining fibers (PMFs) and
polarization controllers (PCs) is presented. The transmission function of this FLM is …
