A new optical local area network that combines dense Wavelength Division Multiplexing (WDM) techniques and coherent transmission benefits is presented. A new multichannel protocol is specified based on Ethernet, using WDM to carry multiple channels on a si ...
Among all non-linear optical effects observed in single-mode optical fibres, stimulated Brillouin scattering (SBS) is of particular importance since it has numerous practical implications. SBS occurs when laser waves are scattered through the interaction o ...
A tunable loss filter based on a long-period fiber grating and a Ti/Pt coating is presented Electrical wavelength tuning of 11 nm with an efficiency of 16.4 nm/W and modulation with 2 s rise time were achieved. ...
Wavelength demultiplexing is a very promising application of photoinduced fiber gratings. In this paper efficient outcoupling of a very narrow wavelength band, in addition to the usual guided Bragg reflection, is presented. The selective outcoupling gratin ...
High-speed optical guided-wave switches and modulators are promising components for present and future applications in lightwave communication and measurement systems, or more generally for optical signal processing purposes. Integrated electro-optic modul ...
Rare-earth doped fibers can be used to realize simple, compact sources of ultrashort pulses. To date, considerable effort has been developed to obtain short pulse generation in Er3+-doped fiber lasers at 1.55 µm. Contrary to this, little work has bee ...
Yeast chromosomes may lack the linker histone H1 (normally required to compact 10 nm beads-on-a-string fiber into the 30 nm fiber) and there is no cytological evidence for higher order fiber structure but they do contain regions which correspond to euchrom ...
The subpicosecond OTDR has been investigated as a diagnostic tool for the fiber optics components and integrated waveguide devices. The mode-locked dye laser at 1.3 μm was excited by Nd-YAG compressed pulses. 300 fsec pulses have been generated at the r ...
We report here the fabrication of fiber chromatic dispersion compensators, along with the tests of those components in wavelength-division-multiplexed transmission at 10 Gb/s and an analysis of their performance by simulation. ...

A novel surveillance system for installed fiber optic cables is presented. It is based on the analysis of the local stimulated Brillouin scattering interaction. The configuration of the instrument rely on the use of a single laser source and the required l ...
