Rare-earth doped optical fibers for temperature sensing

Autor: Leonard George Cohen, D. S. Shenk, Jay R. Simpson, K. W. Quoi, R. A. Lieberman

Publikováno v: Journal of Lightwave Technology. 10:847-852

The feasibility of using a variety of rare-earth doped optical fibers for measuring spatially averaged temperatures from approximately 0 to approximately 100 degrees C over distances of 10 to 20 m is discussed. Such distributed temperature sensors wo

Screening dispersion-shifted fibers for polarization-mode dispersion due to core ellipticity

Autor: W. A. Reed, Leonard George Cohen, D. S. Shenk, K. W. Quoi

Publikováno v: Journal of Lightwave Technology. 8:1684-1687

An attempt to relate polarization dispersion directly to some physical property and then use this as a means by which to characterize polarization-mode dispersion (PMD) is reported. A new diagnostic procedure has been developed and tested for screeni

Publikováno v: Bragg Gratings, Photosensitivity, and Poling in Glass Fibers and Waveguides: Applications and Fundamentals.

The writing of fiber Bragg gratings through the coating has important implications for the mass production of these devices. For instance, the time-consuming steps of stripping and recoating of the grating (potentially leading to fiber strength degra

Noise figure limitation in ytterbium-codoped erbium-doped fiber amplifiers pumped at 1064 nm

Autor: P.F. Wysocki, D. S. Shenk, G. Nykolak

Publikováno v: Optical Fiber Communications, OFC..

Summary form only given. Erbium/ytterbium-doped optical fiber amplifiers (EYDFAs) are attractive because they convert the power available in 1064-nm neodymium-doped sources to 1550 nm. In many potential applications such as CATV, LAN, and WDM systems

Analysis of mode field radius calculated from single-mode fiber far-field radiation patterns

Autor: M. Saifi, W. A. Reed, A. Klemas, D. S. Shenk

Publikováno v: Journal of Lightwave Technology. 3:967-970

We have investigated the angular range and mesh size required to calculate accurate mode field radii (MFR) from single-mode fiber far-field radiation patterns using the inverse Hankel transform. A computer aided fiber modeling program was used to cal

Fiber-optic tapping via induced scattering

Autor: Leonard George Cohen, D. S. Shenk

Publikováno v: Journal of Lightwave Technology. 7:1556-1558

There are many applications in which small amounts of light need to be tapped out of an optical fiber. Linear tapped busses can be attractive if light from a common optical waveguide can be distributed to several spatially separated nodes. A useful a
