摘要：
We demonstrate a polarization insensitive silicon waveguide wavelength filter using a polarization rotator and Bragg grating which exchanges TE0 and TE1 modes. A resonator cavity structure is used to obtain a narrow filter peak width. Two cascaded resonator cavities are used to attain a flat top transmission wavelength peak.
