A compact time delay unit is fundamental to integrated photonic circuits with applications in,
for example, optical beam-forming networks, photonic equalization, and finite and infinite …

This article provides a review and deeper insight on the fundamentals and main design
trade-offs of a new method for joint time-frequency analysis of broadband signals, namely …

The short-time Fourier transform (STFT), or spectrogram (SP), is a very powerful joint time-
frequency signal analysis tool of importance for a wide range of applications, including …

We demonstrate real-time and gap-free continuous frequency-spectrum analysis of
broadband (GHz-bandwidth) microwave signals with unprecedented nanosecond …

This contribution reviews recent work on a new universal analog-processing design for gap-
free real-time spectral analysis of broadband microwave signals, through a continuous …

We propose an approach for relaxing the detection sampling rate in time-mapped
spectrogram analysis. Output spectrograms are fully recovered by sampling at nearly the …

We propose a method for real-time spectral analysis of high-frequency and high-bandwidth
waveforms, without the downconversion stage. Time-mapped spectrograms of nanosecond …
