Abstract

A high-speed, polarization independent, electrooptic tunable filter was built using a birefringence modulator within a Sagnac interferometer. Switching times less than 0.5 ns were achieved in our experiment for this filter. Application in highspeed wavelength routing was also demonstrated.
