Description

technical field [0001] The invention belongs to the technical field of polymer optical waveguide amplifier preparation, and in particular relates to a method for preparing an organic polymer flexible optical waveguide amplifier by using an ultraviolet nano-imprinting technology. Background technique [0002] Erbium-doped fiber amplifier (EDFA) is one of the most important inventions in the history of optical fiber communication. Its length is generally several meters to tens of meters, which is no problem in long-distance communication; In distance transmission, the application of EDFA has certain difficulties. At the same time, in the optical communication system, in order to ensure the transmission of optical signals, it is inevitable to use some optical devices such as multiplexer / demultiplexer, beam splitter and optical switch. Compensation will greatly reduce the transmission distance of the signal, so the signal must be amplified and enhanced. In the optical communic...
