AbstractIn this work, an optical switch based on electro-optic effect is reported. We used defect mode in two-dimensional photonic crystal made of Lithium Niobate. Under an applied voltage of 3 V, a refractive index change of −0.0702 is obtained which has led to a transmittance contrast about 60% for the ON state and a high extinction ratio of about 20 dB. Moreover, Slow light structure performance is investigated to optimize proposed optic switch. Due to elliptic shape of holes, the applied voltage is decreased to 0.5 V. Also, a refractive index change decrease around −0.0481, a transmittance contrast increase 65 %, and an extinction ratio increase by 5 dB have been observed. We used plan wave expansion and finite difference time domain methods to analyze the structures performances. It is seen that a defect mode shift about 40 nm and a switching length of 6.48 μm are obtained with drive voltage of 3 V for simple structure and only 0.5 V for slow light structure.
