Summary :

Temperature dependence of a SAW-controlled optical wavelength demulti-/multiplexer has been discussed. The device consists of ZnS/Ta₂O₅/Nb₂O₅ thin-films on a Y-cut LiNbO₃ substrate. The tuning SAW frequency for the optical switching shifted with temperature by -0.20 MHz/. It is theoretically found that a temperature-independent demulti-/multiplexer can be realized when two waveguides possess the similar temperature properties. When the device is used in a narrow wavelength range, the device constituted of nearly degenerated waveguides exhibits small temperature dependence. These results were experimentally verified. In a nearly degenerated device, the temperature dependence was approximately +0.02 MHz/. The other device having small temperature-dependence was fabricated with a ZnS/Ta₂O₅/Ti-diffused waveguide on a Y-cut LiNbO₃, whose temperature dependence was +0.02 MHz/.
