摘要

This work describes an approach to design a 2 × 2 optoelectronic switch based on the Mach-Zehnder interferometer with a channel profile of Titanium (Ti) diffused in Potassium niobate (KNbO_3) at a wavelength of 1.3 μm. The evaluation parameters used are the insertion loss and the extinction ratio. The originality of this work is introducing the KNbO_3 crystal as a host while optimizing the Ti strip thickness to provide a remarkable switching performance. Optimization leads to a lower switching voltage of 4 V, an insertion loss of 0.0261 dB and extinction ratio of 29.4 dB. The designed switch has a high switching capability and degree of reliability.
