Tunable dispersion compensation by a rotating cylindrical lens.
We present a technique for tunable dispersion compensation that is low cost, high speed, and has a large tuning range. By rotating a cylindrical lens at the Fourier plane of a folded 4f grating pair system, the group-velocity dispersion can be tuned over a range greater than 10(5) fs(2), sufficient for compensating the dispersion of several meters of optical fiber.
