Polarization-Insensitive Lithium Niobate-on-Insulator Interferometer
The key components of a polarization-independent electro-optic (EO) interferometer, including the beam splitter, mode converter, and directional coupler, are designed based on a lithium niobate (LN) Ring platform on an integrated insulator to ensure high extinction ratios.By elaborately designing the geometric structure of the multimode interferenc
