Paper Abstract

Utilization of the photorefractive effect for creation of the waveguiding region may offer rather cheap, easy, "green" (chemicals-free) and flexible way to fabricate the waveguiding-based devices for integrated optics in proper media. We present results of a single waveguide fabrication in LiNbO3:Fe crystal by means of a single Ar+ ion laser beam with special spatial distribution of intensity. The process of the waveguide creation is, in real time, monitored by means of Mach-Zehnder interferometer. According to interpretation of the resulting interferogram this allows to control the time of the exposure needed for reaching the desired difference between the refractive indices of the waveguiding and surrounding regions. The waveguiding properties of the structure are practically demonstrated.
