Interferometers are highly sensitive to phase differences and are utilized in numerous
schemes. Of special interest is the quantum SU (1, 1) interferometer which is able to improve …

We study the polarization dynamics of ultrafast solitons in mode-locked fiber lasers. We find
that when a stable soliton is generated, its state of polarization shifts toward a stable state …

Rogue waves, which were first described as an oceanographic phenomenon, constitute an
important factor in the dynamics of many physical systems. Most of these systems were …

We demonstrate a temporal imaging system that can capture events with unknown time-of-
arrival in the time domain without the need to synchronize the signal. The temporal imaging …

We experimentally demonstrate ghost imaging in the frequency domain based on frequency
speckle patterns as references. Our method is suitable for measuring the spectrum of …

Joint time–frequency representations (JTFRs), such as the spectrogram, provide key
information about the spectral evolution of a system. This is essential for instance to analyze …

Correlated beams are important in classical and quantum communication as well as other
technologies. However, classical amplifiers, which are essential for long transmission of …

Quantum interferometers represent a powerful class of devices that exploit the principles of
quantum mechanics to achieve highly sensitive measurements and precise detection …

Time-lenses were developed rapidly over the last year. They enable measurements of
ultrafast signals which were not measured before with limited electronics detectors. Time …

Macrophages are one of the most important candidates of innate immune response with
pronounced phagocytic activity. As a part of the defense mechanism of our system, an …
