Design and Fabrication of Silicon Photonic Crystal Optical Waveguides Marko Lon?car, Theodor Doll, Jelena Vu ckovic? ?, and Axel Scherer Abstract— We have designed and fabricated waveguides that in-corporatetwo-dimensional(2-D)photoniccrystalgeometryfor lat-eral confinement of light, and total internal reflection for vertical confinement.

We show from the photonic band calculation and the finite difference time domain simulation that polymer photonic crystal slabs with a triangular array of air holes can exhibit complete photonic band gaps for transverse electric-like modes. A line defect introduced in the polymer photonic crystal slab can create guided modes which are useful in implementing low loss waveguides. The light is coupled to the photonic crystal waveguide through a polymer-based fibre coupler and single-mode access strip waveguide butt-coupled to the photonic crystal 11. Details of the Abstract. Tunable photonic band gap generation in Y-Z Lithium Niobate slab through Lamb wave is theoretically studied and presented. The applied 5.5 GHz frequency of Lamb wave able to provide a periodic sinusoidal variation of refractive index through photo-elastic effect in considered 600 nm thick Lithium Niobate slab with period 615 nm.
