Nonlinear optics, the study of intense light-matter interactions, traditionally uses bulk materials like LiNbO3 for device fabrication. However, these materials face challenges such as limited nonlinear susceptibility, large dimensions, and phase matching issues, limiting compact and integrated devices. Recent research…

Instabilities of uniform states are ubiquitous processes occurring in a variety of spatially extended nonlinear systems. These instabilities are at the heart of symmetry breaking, condensate dynamics, self-organisation, pattern formation, and noise amplification across diverse disciplines, including physics, chemistry…

I present a simple view of nonlinear optical phenomena as being determined mostly by the length of interaction time between photons and matter. This may explain why in the last decades the progress in developing better nonlinear materials has been not as rapid as wished. A few tentative routes towards possible…

There is some incertitude on the creation of the term “photonics” and some ambiguity about its frontiers (and differences with respect to optoelectronics and electro-optics). Many authors consider the French scientist Pierre Agrain as the “father” of photonics, as of 1967, even if it would be more correct to refer to…

'Christian Aigner' 'Michael Schmidt'] Dynamic phase-only beam shaping with a liquid crystal spatial light modulator is a powerful technique for tailoring the intensity profile or wave front of a beam. While shaping and controlling the light field is a highly researched topic, dynamic nonlinear beam shaping has hardly…

In this research, an extensive numerical analysis of nonlinear pulse propagation is conducted, focusing primarily on solving the nonlinear Schrödinger equation (NLSE) through the implementation of the split-step Fourier method. The study centers around the interaction between dispersive and nonlinear effects that occur…

Nonlinear optical(NLO) materials are crucial in achieving desired frequencies in solid-state lasers. So far, new NLO materials have been discovered using high-throughput calculations or chemical intuition.

'Timothy P. McKenna' 'Hideo Mabuchi' 'M. M. Fejer'] Abstract: Photonic integrated circuits with second-order ( (2) ) nonlinearities are rapidly scaling to remarkably low powers. At this time, state-of-the-art devices achieve saturated nonlinear interactions with thousands of photons when driven by continuous-wave…

The performance of a laser scanning microscope inevitably depends on the performance of the point detector. As laser scanning approaches aim to penetrate deeper in tissue, there is a commensurate need for detectors that can operate with high sensitivity, bandwidth, and dynamic range at near-infrared wavelengths where…

Nonlinear optical imaging modalities, such as two-photon microscopy and stimulated Raman scattering (SRS) microscopy, make use of pulsed-laser excitation with high peak intensity that can perturb the native state of cells. In this study, we investigated the short and long-term effects of pulsed laser induced…

Tuning of the intramolecular charge transfer (ICT) in a molecule could lead to red-shifted absorption and emission maxima as well as enhanced nonlinear optical (NLO) response. Optimization of the electronic donor (D) and acceptor (A) strength, pi-conjugation and the medium could result in enhancement of first…

Scattering in biological tissues is a major barrier for in vivo optical imaging of all but the most superficial structures. Progress toward overcoming the distortions caused by scattering in turbid media has been made by shaping the excitation wavefront to redirect power into a single point in the imaging plane.…

In our previous work [Ref.~\citenum{MondalJCP2024paper1}], we developed several efficient strategies to simulate exciton-polariton dynamics described by the Holestein-Tavis-Cummings (HTC) Hamiltonian under the collective coupling regime. Here, we incorporated these strategies into the previously developed…

We outline two general theoretical techniques to simulate polariton quantum dynamics and optical spectra under the collective coupling regimes described by a Holestein-Tavis-Cummings (HTC) model Hamiltonian. The first one takes the advantage of sparsity of the HTC Hamiltonian, which allows one to reduce the cost of…

When molecules are coupled to an optical cavity, new light-matter hybrid states, so-called polaritons, are formed due to quantum light-matter interactions. With the experimental demonstrations of modifying chemical reactivities by forming polaritons under strong light-matter interactions, theorists have been encouraged…

In many laser scan engines, mechanical inertia imposes a tradeoff between mirror diameter (mass) and scan speed (cycle time) and/or scan angle amplitude. Ultimately, this limits the field-of-view and/or scan speed in multiphoton and confocal imaging, laser-based manufacturing, and other applications. To push parameters…
