Performance Evaluation of Ti:LiNbO3 Mach-Zehnder Interferometer Switch at 1.3μm, 1.46μm and 1.55μm
In Optical communication, optical switching has become most essential part of optical signal processing. This paper describes 2×2 electro-optic switch based on Mach-Zehnder interferometer with Titanium(Ti) diffused in lithium niobate substrate at 1.3μm, 1.46μm and 1.55μm. Investigations has been done to find the optimum value of switching by varying titanium strip thickness for different wavelengths. By optimization major design parameters, insertion loss and extinction ratio have been evaluated in detail. The proposed switch gives highest extinction ratio of 33.66 dB and insertion loss of 0.0107dB at 1.55μm.
