Continuously tunable 22 ns delay for wideband optical signals using a parametric delay-dispersion tuner

摘要

We present a concept of parametric delay-dispersion tuner (PDDT) that is capable of the continuous tuningnof delay and dispersion for wideband optical signals in a simultaneous and independent manner. We experi-nmentally demonstrate a tunable delay of 22 ns for 2.6 ps return-to-zero optical signals without distortionnand error-free transmissions at 43 gigabits per second. We show that PDDT has a bandwidth of u00010.9 THz,nresulting in the delay-bandwidth product of u000120,000, and exhibits an excellent performance in terms of sta-nbility and reproducibility. © 2009 Optical Society of America
