Fiber Splitter Type

According to the principle, optical splitter can be divided into fused taper type and planar waveguide type [1]. There are two types, the fusion taper type product is made by splicing two or more optical fibers on the side; the planar waveguide type is a micro-optical component type product, which uses photolithography technology to form an optical waveguide on a dielectric or semiconductor substrate to achieve branch distribution. Function. The two types of optical splitting principles are similar. They can achieve different sizes of branches by changing the evanescent field coupling between fibers (coupling degree, coupling length) and changing the fiber radius. Conversely, multiple optical signals can be combined into one signal. called a synth. Fused-cone fiber optic couplers have become the mainstream manufacturing technology in the market because of their simple manufacturing method, low price, easy connection with external optical fibers, and the advantages of being resistant to mechanical vibration and temperature changes.
