Abstract

Polyethylene-glycol (PEG) exhibited bistable transmission characteristics (transparent or opaque) in heating (melting) and cooling (freezing) processes. The bistable temperature range depended on the molecular weight and extended when different types of PEGs were mixed. For example, when PEGs with molecular weights of 300 and 2000 were mixed, the bistability took place in the 2–38 °C range. This phenomenon was used to fabricate a bistable optical fiber switch in which the mixed PEG was put in the gap between the ends of two polymer fibers. The bistable transmission property was demonstrated by controlling the device temperature with a Peltier element.
