“…The remote controls are based on the concept of a wireless switch, composed of a transmitter (remote controller) and a receiver (working device); the controller sends out an encoded signal and the receiver takes/decodes the signal for carrying out the requested commands. − In general, the signal from the transmitter is embedded with the radio or the infrared electromagnetic waves and a typical working distance of the switch, i.e., control range, is of few tens of meters. When the incoming signal from the transmitter is too weak to be processed, the internal amplification unit has to be added to the receiver, which can delay the processing time.…”

Based on the giant persistent photoconductivity (GPPC) characteristic of VO2, we report a remote-control switch that allows high-speed switching on/off functionality. The switch, composed of two VO2 film devices connected in parallel and two semiconductor lasers, can operate multiple electrical devices at near room temperature. The estimated switching-on (off) time of the remote switch is 73 μs (64 μs) with laser intensity of 1.1 × 107 W/m2 at the ambient temperature of 30 °C. The switching-on/off mechanisms can be understood by alternative generation of GPPC at the parallelly connected VO2 devices and the current division rule. Our high-speed remote VO2 switch can be applied to many diverse electronic devices such as safety switches, optical computing, and sensors.
