Abstract

We propose several applications of graded-index (GRIN) time lenses including time–frequency conversion (time-to-frequency conversion and frequency-to-time conversion simultaneously), temporal filtering, and temporal imaging. The evolution of the signal pulses in these systems is demonstrated. As two important parameters, the focal length and the time–frequency conversion factors of time–frequency conversion based on GRIN time lenses are evaluated.
