Paper Abstract

Experimental results on the photorefractive effect in Ti-indiffused LiNbO3, directional couplers at GaAs and He-Ne wavelengths are presented. The photorefractive effect has been observed as drift in the switching state of this device at GaAs wavelengths (0.81 μm and 0.85 μm) for intensities (powers) as low as 32 W/cm2 (3.2 μW). Analysts of this effect indicates refractive index changes as large as 2 x 10-4 are occurring at λ = 0.63 μm. In addition, an analytical model of the mode profiles of Ti-indiffused LiNbO3 channel wave-guides for calculating the coupling characteristics of diffused directional couplers is presented.
