Abstract

The invention relates to a planar rectangular column structure-based on-chip wavelength routing device, belongs to the technical field of micro-nano photonic devices, and discloses the planar rectangular column structure-based on-chip wavelength routing device. The wavelength routing device is capable of realizing an extra small structure of 1*1 micron, is a currently known wavelength routing device with the minimum size, and is suitable for large-scale photonic integration. The device is formed by two materials with different refraction indexes, and is a planar two-dimensional structure consisting of a square and a small rectangular; and through optimally changing the length, width and position of the rectangle, the device is capable of achieving a good beam splitting effect, and a disordered structure which breaks the limitation is obtained.

Description

technical field [0001] The invention relates to an on-chip wavelength routing device based on a planar rectangular column structure, belonging to the field of micro-nano photonic devices. Background technique [0002] Photonic integration technology is at the forefront and the most promising field of optical fiber communication. A photonic integrated circuit is an optical circuit that integrates several optical devices on a substrate to form a whole and make it have certain functions. Compared with traditional electronic circuits, photonic integrated circuits have the advantages of fast speed, high integration and strong anti-interference ability. The rapid development of the field of photonics has made the research and design of photonic devices a hot spot, and the requirements for functional devices in photonic integrated circuits are also getting higher and higher. Wavelength routing, which can separate different wavelengths and propagate them to different output ports,...
