Theory of amplified dispersive Fourier transformation
Amplified dispersive Fourier transformation ADFT is a powerful technique that maps the spectrum of an optical pulse into a time-domain waveform using group-velocity dispersion GVD and simultaneously amplifies it in the optical domain. It replaces a diffraction grating and detector array with a dispersive fiber and single photodetector, greatly simplifying the system and, more importantly, enabl...
متن کاملNoise figure of amplified dispersive Fourier transformation
Amplified dispersive Fourier transformation (ADFT) is a powerful tool for fast real-time spectroscopy as it overcomes the limitations of traditional optical spectrometers. ADFT maps the spectrum of an optical pulse into a temporal waveform using group-velocity dispersion and simultaneously amplifies it in the optical domain. It greatly simplifies spectroscopy by replacing the diffraction gratin...
متن کاملDispersive Fourier Transformation for Versatile Microwave Photonics Applications
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 using chromatic dispersion. Owing to its capability of continuous pulse-by-pulse spectroscopic measurement and manipulation, DFT has become an emerging technique for ultrafast signal generation and processing, and hig...
متن کاملDispersive Fourier transformation for fast continuous single-shot measurements
102 NATURE PHOTONICS | VOL 7 | FEBRUARY 2013 | www.nature.com/naturephotonics The real-time measurement of fast non-repetitive events is arguably the most challenging problem in the field of instrumentation and measurement1–4. These instruments are needed for investigating rapid transient phenomena such as chemical reactions, phase transitions, protein dynamics in living cells and impairments i...
متن کاملAmplified dispersive Fourier-transform imaging for ultrafast displacement sensing and barcode reading
Dispersive Fourier transformation is a powerful technique in which the spectrum of an optical pulse is mapped into a time-domain waveform using chromatic dispersion. It replaces a diffraction grating and detector array with a dispersive fiber and single photodetector. This simplifies the system and, more importantly, enables fast real-time measurements. Here we describe a novel ultrafast barcod...
