Abstract
The paper presents a laboratory model of the time-space converter made as an integrated optics device. Optical signals from a single-mode optical fiber are introduced into a planar waveguide made by titanium doping of lithium niobiate. For high efficiency of coupling from fiber to planar waveguide, directly through the edge, a system of microlenses is used. Deflection of light in the planar waveguide is obtained by an application of ultrasonic surface waves according to the Bragg configuration. Two electrode arrays work with frequencies 124 MHz and 174 MHz and they enable obtaining three positions of the light beam. Outgoing fibers are directly coupled to the edge of the planar waveguide.
