Abstract

Increases in the speed and capacity of ultrahigh-speed optical communication systems have made dispersion compensator technology an essential tool. In view of this fact, we have proposed a virtually imaged phased array (VIPA)-type variable dispersion compensator (VIPA-VDC) capable of trailing a dispersion that changes as a function of time in an optical transmission path, and we have pursued its development. Because the dispersion compensator is comprised of multiple components, an optimal design for the dispersion compensator as a whole is essential to obtaining favorable performance characteristics. Therefore, we have created a simulation algorithm based on Fresnel/Kirchhoff's diffraction integral, calculated the dispersion characteristics of an actual VIPA dispersion compensator, and verified the validity of the simulation algorithm. © 2005 Wiley Periodicals, Inc.
