Optical Dispersion Compensator With$≫$4000-ps/nm Tuning Range Using a Virtually Imaged Phased Array (VIPA) and Spatial Light Modulator (SLM)

We present an optical tunable chromatic dispersion compensator based on a virtually imaged phased-array and spatial light modulator providing both positive and negative dispersion. We demonstrate tunable dispersion compensation of 10-Gb/s positively chirped nonreturn-to-zero data signal over a range of
$-4080sim+850$
ps/nm (240-km single-mode fiber to 9.5-km dispersion-compensating fiber), which operates independent of the input state of polarization and has potential capability for wavelength-division multiplexing.
