Abstract

This paper reviews performance of all-optical modulator based on Magnesium oxide-doped Lithium Niobate ridge waveguides to achieve low V π L at 1550 and 1330 nm wavelengths. The modulation is carried by Mach-Zehnder interferometer structure having 0.4 cm long push-pull arm configuration. The proposed structure is simulated by using beam propagation method. The results of optimization may help in designing electrically tunable optical switch to operate with low switching voltage or an external intensity modulator for optical communication applications.
