Abstract

The analogy between temporal pulse shaping [using dispersive delay lines (DDL) and temporal phase modulators] and spatial beam shaping (using lenses and spatial propagation) was recently developed by Kolner and Nazarathy into the idea of a time lens.¹ Such a system was recently demonstrated by Kauffman et al., who also used the system as a time-to-frequency converter for measuring the intensify versus time of an optical pulse without the need for a high-speed photodetector.²
