Abstract :
Starting from the theory of one-dimensional photonic crystal, a flat-top polarization interleaver filter composed of cascaded thin-film glass cavities is proposed. A detailed design example is given. When rotating the cascaded thin-film glass cavities in the horizontal plane with small angle, the filter has the center-frequency tunability characteristic as well.
