Pulse-by-pulse programmable synthesis of ultrafast optical waveforms
Shilong Liu, Gabriel Demontigny, Émile Dessureault +2
Programmable control of individual pulses in a high-repetition-rate (typically MHz) ultrafast pulse train is a long-standing goal for optical arbitrary waveform synthesis. Here, we…
Single Spatio-Temporal Mode Bright Twin-Beam Source Across the Near- and Mid-Infrared
Gabriel Demontigny, Patrick Cusson, Amauri Perraton Elorza +6
We introduce an ultrafast, bright, entangled twin-beam source generated by type-0 parametric down-conversion in periodically-poled lithium niobate at MHz repetition rate, with cont…
Pulse-to-pulse spectral phase characterization of mid-infrared pulses at megahertz rates
Zhihao Deng, Zicong Xu, Kazuki Hashimoto +3
Pulse-resolved spectral phase measurement of mid-infrared (MIR) pulses is essential for many applications, from precise waveform control to ultrafast quantum optics. However, conve…
Engineering spectro-temporal light states with physics-embedded deep learning
Shilong Liu, Stéphane Virally, Gabriel Demontigny +2
Frequency synthesis and spectro-temporal control of optical wave packets are central to ultrafast science, with supercontinuum (SC) generation standing as one remarkable example. T…
