Optical-electronic printed circuit board, parameter determination method, electronic device, and storage medium

Abstract

Provided are a method for determining parameters of a waveguide core in an optical-electronic printed circuit board, an optical-electronic printed circuit board, an electronic device, and a storage medium. The method includes: determining, according to a refractive index of a material from which the waveguide core is made and a refractive index of a material from which a base layer is made, a critical angle of total reflection at an interface between the waveguide core and the base layer; and determining the parameters of the waveguide core according to a relative positional relationship between one end port of the waveguide core and the other end port of the waveguide core in the optical-electronic printed circuit board, a condition of a region through which the waveguide core passes, and the critical angle, so that steering of the waveguide core is achieved without introducing a curved surface to the waveguide core.
