Integrated all-pass filters for tunable dispersion and dispersion slope compensation

IEEE Photonics Technology Letters, 1999
New integrated optical all-pass filters are presented that can be used for tunable dispersion compensation, dispersion slope compensation, and as building blocks in tunable bandpass filters. The dispersion slope compensation capability is demonstrated using ring resonators in /spl Delta/=2% Ge-doped silica planar waveguides. In addition, a tunable four-

Sampled fiber grating based-dispersion slope compensator

IEEE Photonics Technology Letters, 1999
We propose a novel design for a compact dispersion slope compensator based on sampled fiber Bragg gratings. By chirping the sample function in a sampled grating, we show that the dispersion slope can be controlled to match that of current transmission fibers.

Tunable Dispersion and Dispersion Slope Compensator Using Strain-Chirped Fiber Bragg Grating

IEEE Photonics Technology Letters, 2007
We propose a tunable dispersion and dispersion slope compensator based on induced strain-chirp in a uniform fiber Bragg grating. A specially designed mechanical rotator concatenated with a metal beam with linear thickness variation along its height was used to induce a quadratic strain gradient along the grating.

Reduced dispersion slope, non-zero dispersion fiber

24th European Conference on Optical Communication. ECOC '98 (IEEE Cat. No.98TH8398), 2002
A new reduced-dispersion-slope non-zero-dispersion fiber design, optimized for use in DWDM systems is presented. The low dispersion slope, S/sub 0/=0.045 ps/nm/sup 2/-km, results in significantly less variation in dispersion over the EDFA gain band these fibers can be designed with four-wave-mixing performance superior to large effective area fibers ...
