In the past few decades ultrafast laser physics has blossomed into a mature field, as seen by the Nobel Prizes awarded for chirped pulse amplification (2018) and high-harmonic generation (2023). With the realization of light pulses on the order of a few optical cycles comes an increasing demand for suitable pulse measurement techniques. Since the 1990s, Frequency-Resolved Optical Gating (FROG)...

Synopsis We utilize TIPTOE to directly sample the field of femtosecond bright squeezed vacuum. By resolving the bi-phase nature of the carrier wave, we generate random bit sequences. We perform a full temporal-modal analysis which will allow for random bit generation at PHz rates.

In the last decade, all-optical techniques have been introduced as prospects for quantum random number...

Amplitude-squeezed light provides an opportunity for reducing the shot noise inherent to classical light sources, in turn improving the signal-to-noise ratio. Such amplitude-squeezed states could allow for the use of Stimulated Raman Scattering (SRS) microscopy to be used for imaging light-sensitive samples. These samples could otherwise be damaged due to the intensity needed for using SRS...

807. Ultrabroadband fluorescence-detected two-dimensional electronic spectroscopy

Oral Competition (Undergraduate Student) / Compétition orale (Étudiant(e) du 1er cycle)

Two-dimensional electronic spectroscopy (2DES) has proven to be a powerful tool for studying electronic structure and ultrafast dynamics in a wide range of systems, including natural and artificial light-harvesting complexes, solar cells, molecular systems, quantum dots, and polymers. Fluorescence-detected 2DES (F-2DES) has been shown to provide complementary information to its coherently...

Squeezed states of light are a fundamental resource in photonic-based quantum technologies, enabling the generation and manipulation of non-classical states of light required for universal quantum protocols. A central challenge in realizing robust non-classical states is achieving sufficiently high squeezing while preserving high purity and fidelity. To address this challenge, inline squeezing...
