This paper introduces a 2x2 opto-electronic switch based on Mach-Zehnder interferometer (MZI) with a channel profile of Titanium (Ti) diffused in potassium niobate (KNbO3) at a wavelength of 1.55 μm. The insertion loss and the extinction ratio are the evaluation parameters. The KNbO3 crystal as a host while optimizing the Ti strip thickness to provide a remarkable switching performance. The designed switch has a high switching capability. Optimization leads to a lower switching voltage of 4 V, an insertion loss of 0.044 dB and an extinction ratio of 20.9 dB..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
