We proposed a new conceptual optical switch using phase change of refractive index matching liquid to manipulate the transmission of the optical signals. Compared with the well established vapor bubble based optical switch, the freeze-thaw switch has evident merits in realizing a rapid response and reducing energy consumption rate. The feasibility of the present optical switch was investigated from theoretical interpretation, numerical simulation and conceptual experimental validation. It was demonstrated that this freeze-thaw optical switch could be developed as a very promising device for future optical communication network.
