title: Polarization-diversified photonic comb filter with independently tunable free spectrum range.
abstract: A polarization-diversified photonic comb filter with tunable free spectrum range (FSR) is proposed using two variable differential group delay (DGD) elements in a loop configuration. Two different cosine transfer functions could be simultaneously realized on orthogonal polarization states. Experimental demonstrations also verify feasibilities in various reconfigurable transfer functions.
