Multi-channel dispersion slope compensating optical allpass filter Conference Paper uri icon


  • Compensation of the transmission fiber's dispersion and dispersion slope is critical for high bitrate WDM systems. Techniques include specially designed fibers with a large negative dispersion and dispersion slope, and single-channel devices (or devices for a small or limited number of channels) such as chirped fiber Bragg gratings or lattice Mach-Zehnder filters [1]. In this paper, we present a new device based on a Gires-Tournois interferometer [2], or optical allpass filter, that is capable of compensating a large number of channels without requiring a demultiplex and re-multiplex operation.
