The photonic router is a key device in optical communication and quantum networks. Here, the results of a study of multi‐channel optical routing using optomechanical multimode interference in an optical microcavity are reported. The optomechanical system used here exhibits multi‐optical modes and a mechanical mode. Optomechanical induced transparency and absorption appear in the system due to the interference between different paths. It is shown that the system can be served as a three‐port routing in the red‐detuned region to rout photons from the input port to an arbitrarily selected output port with high routing efficiency by controlling the parameters corresponding to different interference paths.
