Dispersion characteristics of single-mode As2S3 fiber

In this paper, we measure the dispersion characteristic of chalcogenide fiber. We use phase shift method to measure the dispersion characteristic of single mode As2S3 fiber around 1 .55 im. Measurement show the strong dispersion of about -39 ps/kmnm at communication wavelength of 1 .55 um. Chalcogenide fiber has promising market as dispersion compensation device with such good performance.
