Abstract
PURPOSE:To make construction simple and enable signal switching to be performed with good efficiency by constituting plural thin film optical guides on the surface of an electro-optic crystal body in a matrix shape so as to intersect with respect to other, providing electrodes generating surface elastic waves adjacently on the surface of the intersecting parts and changing-over the light signals by the operations of the electrodes. CONSTITUTION:Plural thin film optical guides 2-5 are formed in a matrix shape on the surface of an electro-optic crystal 1 of LiNbO3, LiTaO3 or the like by a diffusion or ion implantation method of Ti etc. so as to intersect with respect to other. Comb-shaped electrodes 11-11-16-17 which are patterned with Al film and excite surface elastic waves are so provided on the surface of the substrate 1 in proximity with said intersecting parts 6-9 so as to diametrally oppose by way of the intersecting parts in-between. The signals inputted from input ends 2a-5a may be changed over to desired directions of output ends 2b-5b by applying AC voltage selectively to these electrodes. This device is simple in construction and permits changing-over of signals with good efficiency.
