Applications of temporal imaging in optical signal processing

In this paper, the authors use temporal imaging concepts in building the novel instrumentation for optical signal processing. Two temporal imaging devices are used, time-lenses and time-prisms. For one instrument, the authors use a time-lens to build a multiwavelength pulse generator ideal for WDM parallel processing that eliminates the need for mode-locking or nonlinear spectrum generation used in current similar sampling instruments. In another device, the authors use a time-prism pair to achieve a programmable ultrafast optical delay line.
