Analysis and Design of an Electro-Optic 2x2 Switch Using Ti: KNbO3 as a Waveguide Based on MZI at 1.3 µm
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 (KNbO3) at a wavelength of 1.3μm. The evaluation parameters used are the ion loss and the extinction ratio. The originality of this work is introducing the KNbO3 crystal as a host while optimizing the Ti strip thickness to provide a remarkable switching performance. Optimization leads to a lower switching voltage of 4V, an ion loss of 0.0261dB and extinction ratio of 29.4 dB. The designed switch has a high switching capability and degree of reliability.
