Abstract

A study of find adjustment of the coupling coefficient of Zn-diffused directional couplers on Z-cut lithium niobate substrate by a series of post thermal-treatment is presented for the first time. Optical mode profiles and propagation losses before and after the treatments are measured for the 1.32 (mu) m wavelength. Experimental results show that the post thermal-treatment is quite efficient for fine adjustment of the cross coupling power ration of the directional coupler.
