title: Time-frequency conversion, temporal filtering, and temporal imaging using graded-index time lenses.
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.
