Abstract :
A new compact AO filter with multi-reflector beam expanders built by photonic crystal row of holes in LiNbO3 waveguide had been proposed and numerically studied by 2D FDTD method. Device has the size 70*150 μm2, FWHW 4.4 nm, tuning range 110 nm, internal loss -3dB, and sidelobes -20 dB and has a great potential for use in telecommunication and sensorings.
