Review of Chromatic Dispersion Measurements Techniques
نویسنده
چکیده
Chromatic dispersion measurements require experimental conditions which meet with particular difficulties, that is, a wide spectral coverage and a picosecond time resolution over a kilometer-length fiber. This paper shows what makes of these measurements an experimental challenge and the main solutions found since the tate seventies are reviewed. Pulse propagation, interferometric and phase-shift methods are in particular described, showing their respective advantages and limitations. Recent progresses and latest developments in the domain are then presented, such as the double optical modulation and other advanced techniques, which promise close-to-ideal conditions for this

Design of Single Mode Photonic Crystal Fiber with Outstanding Characteristics of Confinement Loss and Chromatic Dispersion over S to L Communication Band
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...
متن کاملImprovement of Optical Properties in Hexagonal Index-guiding Photonic Crystal Fiber for Optical Communications
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 ...
متن کاملVirtual Reference Interferometry: Theory & Experiment
This thesis introduces the idea that a simulated interferogram can be used as a reference for an interferometer. This new concept represents a paradigm shift from the conventional thinking, where a reference is the phase of a wavefront that traverses a known path. The simulated interferogram used as a reference is called a virtual reference. This thesis develops the theory of virtual reference ...
متن کاملAll-Fiber Interferometer for Chromatic Dispersion Measurements
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. Re...
