Abstract

A fast 2x2 free-space photonic switch based on ferroelectric liquid crystal (FLC) is demonstrated with switching times of order of microseconds. An examination of the insertion loss and crosstalk properties of the switch reveals an average loss and crosstalk of < 0.45 dB and -33 dB, respectively. Such low-loss and low-crosstalk properties indicate that the switch is suitable for a larger-scale matrix switch design. We discuss incorporation of the demonstrated switch into a multistage network configuration and the properties of optical components required for achieving up to 1000 channel matrix switches.
