Abstract

A low dispersion comb filter or interleaver comprises a first birefringent element assembly (3) having at least one birefringent element (4-6) and a second birefringent element assembly (10) having at least one other birefringent element (11-13). The first birefringent element assembly and the second birefringent element assembly are configured so as to cooperate with one another in a manner which mitigates dispersion of the interleaver. By aligning the polarization directions of the odd channels and the even channels so as to be parallel with respect to another prior to entering the second birefringent element assembly, zero or nearly zero dispersion is obtained simultaneously for both the odd and even channels.
