Abstract

Epitaxial Ba_0.7Sr_0.3TiO₃ (BST) thin films were deposited on MgO (001) single crystal substrates using pulsed laser deposition. The bidimensional structure of a rib-type Mach-Zehnder electro-optic modulator was designed using the effective index method. A Mach-Zehnder electro-optic modulator based on BST/MgO was fabricated using standard photolithography and reactive ion etching techniques. A single mode near-field output pattern was observed using an end-fire coupling method. Optical modulation was successfully demonstrated. The half-wave voltage V_π was found to be 60 V and the effective electro-optic coefficient was calculated to be r_c^eff = 27.0 10^-12 m/V at a wavelength of 1550 nm.
