Using longer wavelengths to write fiber Bragg gratings could ease the process-if researchers can speed up the writing at these wavelengths. By doping the fiber with holmium and...
Band WDM products utilize proprietary thin-film filter technology to achieve wavelength and channel isolation and stability. The 100- and 200-GHz (4 Skip 0) Band WDM products ...
The technique of interleaving wavelengths is an effective way to narrow e×isting 200- or 100-GHz DWDM systems down to 50-, 33-, or 25-GHz channel spacing. To accomplish this goal...
Researchers at NTT Photonics Laboratories in Ibaraki, Japan, have invented an arrayed-waveguide device that operates over a wide wavelength range, produces a stable, narrowband...
Falling prices coupled with a market slowdown during the last 18 months have driven a major shift in component manufacturers' priorities. Reducing production costs has replaced...
How are you? In any language, the question is usually a casual form of greeting and the person posing it doesn't expect a real answer. Yet these days it is the question that we...
Lensed and tapered specialty fibers are designed to optimize coupling between the fiber and optical components such as edge-emitting laser diodes and the waveguides in an integrated...
The evolution to higher data rates such as 40 Gbit/s requires a number of new engineering solutions. Among them is a change to return-to-zero (RZ) coding format. As with all technical...
