All-Fiber Interferometer for Chromatic Dispersion Measurements
نویسنده
چکیده
Abstrucf-A new all-fiber interferometric method for chromatic dispersion measurements in meter-length single-mode fibers is presented. In a Michelson setup a reference fiber is used whose physical length is varied so as to obtain an adjustable optical delay. Time resolution, ease of manipulation, and mechanical isolation are considerably improved with respect to conventional interferometers. Resolution of group delay measurement and Chromatic dispersion over the full 1100-1700 nm spectral range are better than 5 fs and 0.1 ps/nm . km, respectively.

Measurement of chromatic dispersion of microstructure optical fibers using interferometric method
We present a modification of the interferometric method for the measurement of optical fiber chromatic dispersion using an easily aligned, almost all-fiber Michelson interferometer. Particular issues of the microstructure fiber characterization are discussed. Accuracy of the method is validated by comparing the chromatic dispersion measurement of the standard single-mode fiber with results obta...

In this article, a novel structure of photonic crystal fiber with nearly zero ultra-flattened chromatic dispersion and ultra-low confinement loss is presented. By replacing the circular air-holes of two first rings with the elliptical air-holes, a fiber with outstanding features of chromatic dispersion and confinement loss is designed. The proposed structure is optimized for operating in a wide...

Waveguides with low confinement loss, low chromatic dispersion, and low nonlinear effects are used in optical communication systems. Optical fibers can also be employed in such systems. Besides optical fibers, photonic crystal fibers are also highly suitable transmission media for optical communication systems. In this paper, we introduce two new designs of index-guiding photonic crystal fiber ...
