Abstract: The use of a uniaxial birefringent material such as lithium niobate $({\mathrm{LiNbO}}_{3},\phantom{\rule{4pt}{0ex}}\mathrm{LN})$ as the core of a microring resonator leads to coupling between transverse-electric and transverse-magnetic modes. We develop a theoretical framework to study polarization… read more here.

DOI: 10.1103/physrevb.99.195307
Abstract: In anisotropic or bianisotropic waveguides, the standard coupled mode theory fails due to the broken link between the forward and backward propagating modes, which together form the dual mode sets that are crucial in constructing… read more here.
