Rigorous electromagnetic methods are applied to calculate the propagation constants and
the fields of the allowed guided modes in uniaxial slab waveguides for an arbitrary …

We discuss several types of integrated photonic LiNbO_3 waveguides supporting
propagation of modes which can be classified as bound states in the continuum (BICs). The …

The guided-to-leaky hybrid mode transition in slab optical waveguides made on uniaxial
crystals such as LiNbO/sub 3/, or LiTaO/sub 3/, is analyzed. Two different guided-to-leaky …

The propagation characteristics of the leaky modes in planar anisotropic waveguides with a
multilayer structure have been investigated by means of a compact rigorous formalism. The …

Birefringence phase-matching based\c {hi}(2) ZnGeP2 (ZGP) waveguide platform has been
recently reported for excellent mid-infrared laser generation. Here, a detailed theoretical …

The generalization of the WKB method for light propagation in planar uniaxially anisotropic
inhomogeneous optical waveguides is presented. Both ordinary and extraordinary ray paths …

Polarization independent switch or coupler including a directional coupler with extremely
relaxed fabrication tolerances. The coupler includes a mono-crystalline wafer of electro-optic …

The occurrence of semileaky waves in dielectric chirowaveguides is investigated. It is shown
that a thin-film dielectric chiroslabguide with an achiral superstrate and in which both the film …

The field theory of guided waves in optical fibers with step-index profiles and in which both
core and cladding are chiral isotropic media is developed. We show that both surface and …

The existence of totally guided waves, TE-dominant, in properly tailored structures
containing an ultrathin dielectric film of low refractive index deposited onto an anisotropic …
