Three-dimensional optical waveguide manufacturing method

Abstract

The invention discloses a three-dimensional optical waveguide manufacturing method. A three-dimensional optical waveguide comprises a waveguide body, a base body, a waveguide lateral branch and waveguide longitudinal branches. The refractive index of the waveguide body is higher than that of the base body. When light is incident from one end of the waveguide body, the light forms total reflectionon the interface between the waveguide body and the base body, so light can be transmitted internally along the waveguide body; the waveguide lateral branch and the waveguide longitudinal branches aredistributed on the waveguide body, the light is split into two beams according to a certain power ratio when the light meets the branches when the light is transmitted along the waveguide; the 3D printed three-dimensional optical waveguide is a multi-layer three-dimensional optical waveguide structure formed by first linearly stacking materials to form a layer in sequence by a 3D printer and stacking the layers in sequence, wherein the position at which the waveguide body is located is a hollow pipe after printing; waveguide materials are poured into the hollow pipe along a filling port and solidified to form the waveguide body; and the six faces of the optical waveguide structure are further ground and polished to achieve the effect of connecting an externally connected optical waveguidefor light transmission.

Description

technical field [0001] The invention relates to the fields of optoelectronic integrated circuit boards and the like, in particular to a method for manufacturing a three-dimensional optical waveguide. Background technique [0002] Science and technology in the 21st century are changing with each passing day. As a high-tech industry, the electronics industry is experiencing rapid technological development. At present, with the rapid and comprehensive development of multimedia services, including telephone, cable TV (CATV), digital TV and Internet, the requirements for circuit bandwidth and capacity have increased dramatically. In the traditional field of electricity, the speed of signal transmission and switching has been limited. Taking electronic computers as an example, the main frequency of its CPU has reached 2-2.9GHz, and the speed of transmitting code streams on the telecommunications trunk line has even reached dozens or even thousands of Gbits. In contrast, the bus ...
