Temporal Optical Superoscillations
We consider possible applications of temporal superoscillatory optical signals. First we discuss the delivery of a super-oscillatory optical signal through a medium with an absorbing resonance at the super-oscillation frequency. While a regular signal oscillating at the absorption resonance frequency would be completely absorbed after a few absorption lengths, it is found that the superoscillation undergoes quasi-periodic revivals over optically thick distances. In the second part of the talk we present experimental results where the use of a superoscillating optical beat breaks the optical temporal Fourier resolution limit by an unprecedented 75%. Such superoscillatory beats can substantially increase the temporal resolution of light-driven measurement and control processes.
