Abstract

An interferometric time measurement of the intermodal dispersion in a 40-m telecommunication fiber at 560 nm is reported. Six modes are identified as LP modes by their spatial interference pattern and are clearly time resolved. To overcome laser noise and low interference contrast, a new interferometric time measurement technique has been developed. The image of the interference fringe pattern is analyzed by a CCD photodetector array. Interference fringes produce a modulation at the CCD's output that can be filtered and averaged to retrieve accurate time information.
