Real-time Fourier transformation (RTFT) of signals is a fundamental concept that enables
Fourier analysis at speeds beyond the limitations of conventional digital signal processing …

Broadband radio-frequency chirped waveforms (RFCWs) with dynamically tunable
parameters are of fundamental interest to many practical applications. Recently, photonic …

The recent demonstration of external cavity quantum cascade lasers with optical feedback,
controlled by an acousto-optic modulator, paves the way to ruggedized infrared laser …

The ever‐increasing demand for high resolution and real‐time recognition in radar
applications has fuelled the development of electronic radars with increased bandwidth …

We provide a theoretical study of frequency-shifted feedback (FSF) lasers, ie, lasers with an
internal frequency shifter, seeded with a monochromatic wave. The resulting spectrum …

This paper presents recent results in the development of novel ultrafast technologies based
on the generation and application of extremely chirped optical pulses. Linearly frequency …

We show both theoretically and experimentally that frequency-shifted feedback (FSF) lasers
seeded with a single frequency laser can generate Fourier transform-limited pulses with a …

Recirculating frequency-shifting loops (FSLs) are a simple source of optical frequency
combs with bandwidth compatible with microwave technologies. As such, they have …

The results of an optoelectronic system—frequency-shifted feedback (FSF) laser
experimental examination are presented. The considered FSF laser is seeded only with …

The formation of stationary and non-stationary pulse groups is regularly observed in multiple
pulse soliton fiber lasers. The environment developed in this study for the flexible …
