Ultrafast optics has undergone a revolution in the past two decades, driven by new methods
of pulse generation, amplification, manipulation, and measurement. We review the …

Manipulation and characterization of information using ultrafast optical signals is critical for
numerous applications in telecommunications, biology, quantum information science …

Today's exploding demand for faster, more reliable, and ubiquitous radio systems in
communication, instrumentation, radar, and sensors poses unprecedented challenges in …

The last two decades have seen a wealth of optical instrumentation based upon the
concepts of space-time duality. A historical overview of how this beautiful framework has …

Real-time optical spectrum analysis is an essential tool in observing ultrafast phenomena,
such as the dynamic monitoring of spectrum evolution. However, conventional method such …

We present highly efficient time-lenses for orthogonal polarized signal waves with a specific
state of polarization. Our four-wave mixing based time-lenses exploit polarization mode …

This paper reports on the utilization of the time-domain optical Fourier transformation (OFT)
technique for serial-to-parallel conversion of optical time division multiplexed (OTDM) data …

We demonstrate a novel method for spectral analysis of microwave signals that employs
time-domain processing in fiber. We use anomalous dispersion in single-mode fiber to …

We introduce and formalize a time-frequency dualism between first-order dispersion and
quadratic phase modulation (time lens). As a particular case of this dualism, we demonstrate …

We experimentally demonstrate a spectral magnifier using an imaging system with two time-
lenses based on four-wave mixing in a Si nanowaveguide. We achieve a magnification …
