Abstract
An apparatus includes an optical waveguide and an optical filter positioned to receive light from the optical waveguide. The optical waveguide includes a sequence of alternating first and second stripes. The sequence runs along a propagation direction in the optical waveguide. The first and second stripes are formed of different polarization states of a group III-nitride semiconductor. The optical filter removes light of a preselected frequency.
