Abstract

Abstract

The loss mechanism of bent waveguide including the bending loss, propagation loss, radiation loss and the loss of mode conversion are theorically analysed in this paper. It focuses on the review of the design of low loss bent waveguide, including materials, the shape of bent waveguide, strip or rib waveguide, the width, height and radius of the bent waveguide, the dismatch of mode, the shape of the curve and other new structures. The representative works on the design and fabrication of low loss bent waveguides are summarized. The development status of the low loss bent waveguide is analysed and its applications in integrated optical are introduced. The future developing trend of bent waveguide is to develope the theory of the loss characterization and wave coupling, and to realize low bending loss with very small bending radii for high desity integration in Photonics Integrated Circuits (PICs).
