Abstract

We report on a chromatic dispersion slope compensator fabricated with a silica waveguide. The compensator was composed of two arrayed-waveguide grating wavelength filters and an array of delay lines. Output ports of the first filter were jointed to input ports of the second filter through the delay lines. Each wavelength component demultiplexed at the first filter was assigned with delay, which was needed for realizing the dispersion slope compensation characteristics. The obtained dispersion slope and bandwidth were -3.03 ps/nm² and 19.8 nm, respectively, at 1.55 μm. The compensator has the ability to equalize the dispersion slope of about a 43 km-long dispersion-shifted fiber.
