摘要： Disclosed is a compact on-chip polarization splitter-rotator based on a Bezier curve gradient waveguide. The Bezier curve gradient waveguide structure is a standard SOI-based wafer structure, comprising a substrate, of which the bottom layer is buried with oxide (SiO2), and the top is composed of silicon waveguides, including a common output waveguide and a specially-structured waveguide containing Bessel curve boundaries. The common waveguide structure is composed of a cuboid waveguide, and the specially-structured waveguide is composed of an input region, an output region, a width-gradient waveguide (Bezier curve gradient structure) and a coupling region, where a width of the gradient waveguide is determined by a third-order Bezier curve, and the coupling region is composed of two asymmetrical waveguide regions.

摘要： Disclosed is a Chinese knot-like porous fiber core ultra-high birefringence THz optical fiber. The optical fiber comprises a substrate, claddings and fiber cores, wherein the claddings and the fiber cores are arranged in the substrate, and the fiber cores are embedded in the centers of the claddings; and the fiber core comprises a first fiber core region, a second fiber core region and a third fiber core region, the center of the first fiber core region 4 serves as the origin of coordinates, and the first fiber core region 4 is composed of six regular hexagon units with overlapped boundaries in the x-axis direction. In the present disclosure, the fiber core comprises a first fiber core region, a second fiber core region and a third fiber core region, and the three regions jointly form a fiber core region of a Chinese knot-like porous fiber core.
