Embodiment Construction

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0021] One of the core links of optical fiber communication is the mutual conversion of optical and electrical signals. Optical fiber communication uses optical signals that carry information to transmit in information transmission equipment such as optical fibers / optical waveguides. The passive transmission characteristics of light in optical fibers / optical waveguides can realize low-cost, low-loss information transmission; while computers and ot...
