3D simulation of low loss photonic crystal-based splitters on lithium niobate in mach-zehnder interferometer Available to Purchase

We present 3D simulation of low loss splitters made on Lithium Niobate used in Mach-Zehnder interferometers. The interferometer consists of the splitters designed with photonic crystal structures at splitting point and bend positions for reduced size and loss, and straight sections as channel waveguides with high electro-optical coefficient r₃₃ of Lithium Niobate for reduced interactive length and modulating voltage π. The simulation shows a reduced coupling loss to 1.37 dB with the channel waveguides made suspended and V_π?is only 0.42V for interactive length of 200 um.
