Slotsuppression of Scattering Loss in the Side Wall of Bent Slot Waveguide

Abstract

With the higher requirements of advanced integrated circuit technology, waveguides can propagate electromagnetic waves with higher frequencies, such as millimeter waves and centimeter waves, and have a large power capacity, which makes waveguides a common transmission line in the microwave band. In this experiment, based on the research of the curved slot waveguide, the method of suppressing the scattering loss of the side wall is studied. The wave optics module is used to model the optical waveguide, and the mode of the designed curved slot waveguide is analyzed, and the thickness of each layer of the optical waveguide is optimized according to the material characteristics to reduce the influence of the high refractive index substrate and reduce the curvature of the side wall Absorption of scattering loss to avoid the influence of resonance. The curved slot waveguide curved microring resonator and the curved slot waveguide racetrack microring resonator are studied, and the device performance parameters are simulated and analyzed. In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a sidewall scattering loss based on a curved slot waveguide and a preparation method. The side scattering characteristics of the waveguide multilayer memory are experimentally studied. The results show that the distribution of the scattered light intensity from the side of the waveguide along the propagation direction of the guided light exhibits an exponential decay law, and its attenuation constant is proportional to the information symbol density, and the curved slot used for recording information increases and grows.
