Variable wavelength-spacing tunable filter using polarization differential delay line

Paper Abstract

A tunable filter that can be applied for dispersion compensation, a multiwavelength laser source, or a channel transmitter/attenuator is proposed. Channel spacing and dispersion can be controlled simultaneously by using a motorized polarization differential delay line and a variable coupler in the loop mirror. Due to its periodic characteristic, chromatic dispersion of multiple channels can be compensated all at once.
