Abstract :
We demonstrate a tunable, optical delay element using selective wavelength conversion in a PPLN waveguide, dispersion compensating fiber, and intra-channel dispersion compensation. A continuous delay of up to 105-ns, equalling >4000 bit-slots at 40-Gb/s, is demonstrated using 80- Gb/s RZ-DQPSK, 40-Gb/s RZ-DPSK and 40-Gb/s RZ-OOK modulation formats.
