Abstract

An optical waveguide and a printed circuit board. The optical waveguide comprises a lower clad layer (1), an upper clad layer, and a waveguide core layer formed between the lower clad layer (1) and the upper clad layer. The waveguide core layer comprises at least one waveguide unit (100). Each waveguide unit (100) comprises a signal optical waveguide used for transmitting an optical signal, and a gain optical waveguide (3) used for amplifying, under a pump effect of pump light, the optical signal transmitted by the signal optical waveguide. The signal optical waveguide and the gain optical waveguide (3) are disposed on the surface of the side of the lower clad layer (1) facing the upper clad layer, and the signal optical waveguide and the gain optical waveguide (3) are connected into an integral structure by means of end surfaces, so that normal operation of the system can be ensured, and the optical interconnection bottleneck problem caused by great loss of optical signal transmission can be avoided.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to an optical waveguide and a printed circuit board. Background technique [0002] With the continuous improvement of the demand for high-speed data transmission, data centers need multiple processors to cooperate to complete the processing of related data, which makes the data center's requirements for the interconnection bandwidth between chips become higher and higher. Therefore, printing in the system The interconnection rate, bandwidth and channel density between printed circuit boards (Printed circuit board, PCB) and / or between chips on the PCB all put forward higher requirements. [0003] The traditional electrical interconnection method based on metal wires between chips on the PCB has serious transmission loss and limited transmission distance during high-speed data transmission due to the inherent physical characteristics of the metal wire itself (the higher the transm...
