Abstract
A new method for providing a continuously variable, true time delay for radio frequency (RF), microwave, and millimetre wave signals using fibre optics is proposed and demonstrated. Variation in time delay up to 1.7 ns and millisecond-order modulation speeds are demonstrated for signals to 20 GHz.
