Problems solved by technology

However, the disadvantage of this structure is that the microring resonator requires input / output waveguide for coupling. In order to achieve high coupling efficiency, it is necessary to strictly control the distance between the microring and the input / output waveguide, and the distance is usually very small, that is, increasing The processing difficulty of the device and the cost of device preparation

Abstract

The invention provides an integratable coupling microcavity optical filter which comprises a microcavity and a waveguide. The microcavity comprises an inner ring and an outer ring, and the outer ring is in a helical shape. The integratable coupling microcavity optical filter adopts the helical microcavity, and the notch is directly connected with input and output waveguide, thereby improving the coupling efficiency. The helical microcavity is directly connected with the waveguide, has the directional input and output property, and also has the advantages of high Q value and narrow linewidth. The structure is compact, is easy to integrate, does not need to couple input / output by waveguide, reduces the processing degree of devices, decreases the preparing cost of the devices, and is especially suitable for preparing multi-functional filters with high-property integrated optical chips.

Description

technical field [0001] The invention belongs to the field of optical communication and information processing devices, and in particular relates to an integrable coupling microcavity optical filter. Background technique [0002] The rapid development of optical communication and information processing has put forward new requirements for optoelectronic devices. These requirements include high efficiency, fast response, miniaturization, high integration and low cost. As a new type of integrated optical device, the optical microcavity based on Whispering-Gallery Modes (hereinafter referred to as WGM) has attracted extensive attention from scholars at home and abroad. The so-called whispering gallery optical microcavity refers to a resonant cavity whose geometric scale can be compared with the wavelength of light and has a high quality factor (Q). The optical microresonator is generally composed of a high-refractive-index light-guiding layer and a low-refractive-index confine...
