Dispersive Fourier transformation is an emerging measurement technique that overcomes
the speed limitations of traditional optical instruments and enables fast continuous single …

Optical imaging is arguably the most effective tool to visualize living cells with high
spatiotemporal resolution and in a nearly noninvasive manner. Driven by this capability …

A time-domain equivalent of the spatial Talbot or self-imaging phenomenon appears when a
periodic temporal signal propagates through a dispersive medium under first-order …

Based on time-space duality, we deduce a time-domain equivalent to the Fraunhofer (far-
field) approximation in the problem of spatial diffraction. We can use this equivalence to …

In this paper, we propose and demonstrate an approach to optically generating chirped
microwave pulses with tunable chirp profile based on optical spectral shaping using a …

We propose and analyze a new technique for optical pulse shaping that uses fiber Bragg
gratings, which overcomes the depletion effects associated with long uniform gratings …

The so-called space-time analogy constitutes a source of inspiration to understand,
engineer, and implement new systems for ultrafast optical signal processing based on …

The frequency-to-time mapping technique (also known as the temporal far-field
phenomenon) usually requires a significant amount of dispersion to stretch an ultrashort …

Dispersive Fourier transformation (DFT) maps the broadband spectrum of an ultrashort
optical pulse into a time stretched waveform with its intensity profile mirroring the spectrum …

We demonstrate the use of dispersive microstrip as a mechanism for obtaining the real-time
Fourier transform of a time-limited signal within a predefined bandwidth. By etching a …
