102. Numerical Simulations of Light Bullets, Using The Full Vector, Time Dependent, Nonlinear Maxwell Equations

Author

Goorjian, Peter M, Silberberg, Yaron, and Kwak, Dochan

Subjects
Optics
Abstract

This paper will present results in computational nonlinear optics. An algorithm will be described that solves the full vector nonlinear Maxwell's equations exactly without the approximations that we currently made. Present methods solve a reduced scalar wave equation, namely the nonlinear Schrodinger equation, and neglect the optical carrier. Also, results will be shown of calculations of 2-D electromagnetic nonlinear waves computed by directly integrating in time the nonlinear vector Maxwell's equations. The results will include simulations of 'light bullet' like pulses. Here diffraction and dispersion will be counteracted by nonlinear effects. The time integration efficiently implements linear and nonlinear convolutions for the electric polarization, and can take into account such quantum effects as Karr and Raman interactions. The present approach is robust and should permit modeling 2-D and 3-D optical soliton propagation, scattering, and switching directly from the full-vector Maxwell's equations.

115. Single-pulse coherent anti-Stokes Raman spectroscopy in the fingerprint spectral region.

Abstract

Quantum coherent control techniques are applied to achieve high spectral resolution nonlinear vibrational spectroscopy using a single ultrashort laser source. By controlling the spectral phase of ∼10 fs pulses, we are able to obtain detailed coherent anti-Stokes Raman (CARS) spectra in the important fingerprint spectral region, which reflects the structural chemical information. A full theoretical analysis and an experimental demonstration of two alternative schemes leading to spectral resolution two orders of magnitude better than the pulse bandwidth are presented. The first involves selective excitation of vibrational levels within the pulse bandwidth by periodic modulation of the spectral phase of the pulse. In the second scheme an effective narrow probing of the vibrational level has been achieved by phase shifting of a narrow spectral band. Single-pulse CARS offers an attractive alternative to conventional multibeam nonlinear vibrational spectroscopy techniques. [ABSTRACT FROM AUTHOR]

129. Super-resolution enhancement by quantum image scanning microscopy.

Author

Tenne, Ron, Rossman, Uri, Rephael, Batel, Israel, Yonatan, Krupinski-Ptaszek, Alexander, Lapkiewicz, Radek, Silberberg, Yaron, and Oron, Dan

Abstract

The principles of quantum optics have yielded a plethora of ideas to surpass the classical limitations of sensitivity and resolution in optical microscopy. While some ideas have been applied in proof-of-principle experiments, imaging a biological sample has remained challenging, mainly due to the inherently weak signal measured and the fragility of quantum states of light. In principle, however, these quantum protocols can add new information without sacrificing the classical information and can therefore enhance the capabilities of existing super-resolution techniques. Image scanning microscopy, a recent addition to the family of super-resolution methods, generates a robust resolution enhancement without reducing the signal level. Here, we introduce quantum image scanning microscopy: combining image scanning microscopy with the measurement of quantum photon correlation allows increasing the resolution of image scanning microscopy up to twofold, four times beyond the diffraction limit. We introduce the Q-ISM principle and obtain super-resolved optical images of a biological sample stained with fluorescent quantum dots using photon antibunching, a quantum effect, as a resolution-enhancing contrast mechanism. Characterizing not only the fluorescence intensity but also the inherent quantum correlations of the fluorescent photon stream can enhance the spatial resolution of image scanning microscopy up to twofold, a fourfold improvement over the diffraction limit.

Abstract

Quasiperiodic lattices have recently been shown to be a nontrivial topological phase of matter. Charge pumping—one of the hallmarks of topological states of matter—was recently realized for photons in a one-dimensional off-diagonal Harper model implemented in a photonic waveguide array. However, if the relationship between topological pumps and quasiperiodic systems is generic, one might wonder how to observe it in the canonical and most studied quasicrystalline system in one dimension—the Fibonacci chain. This chain is expected to facilitate a similar phenomenon, yet its discrete nature hinders the experimental study of such topological effects. Here, we overcome this obstacle by utilizing the topological equivalence of a family of quasiperiodic models which ranges from the Fibonacci chain to the Harper model. Implemented in photonic waveguide arrays, we observe the topological properties of this family, and perform a topological pumping of photons across a Fibonacci chain., MINERVA Foundation (Germany), United States.

Abstract

The dynamics of filopodia interacting with the surrounding extracellular matrix (ECM) play a key role in various cell-ECM interactions, but their mechanisms of interaction with the ECM in 3D environment remain poorly understood. Based on first principles, here we construct an individual-based, force-based computational model integrating four modules of 1) filopodia penetration dynamics; 2) intracellular mechanics of cellular and nuclear membranes, contractile actin stress fibers, and focal adhesion dynamics; 3) structural mechanics of ECM fiber networks; and 4) reaction-diffusion mass transfers of seven biochemical concentrations in related with chemotaxis, proteolysis, haptotaxis, and degradation in ECM to predict dynamic behaviors of filopodia that penetrate into a 3D ECM fiber network. The tip of each filopodium crawls along ECM fibers, tugs the surrounding fibers, and contracts or retracts depending on the strength of the binding and the ECM stiffness and pore size. This filopodium-ECM interaction is modeled as a stochastic process based on binding kinetics between integrins along the filopodial shaft and the ligands on the surrounding ECM fibers. This filopodia stochastic model is integrated into migratory dynamics of a whole cell in order to predict the cell invasion into 3D ECM in response to chemotaxis, haptotaxis, and durotaxis cues. Predicted average filopodia speed and that of the cell membrane advance agreed with experiments of 3D HUVEC migration at r[superscript 2] > 0.95 for diverse ECMs with different pore sizes and stiffness., Singapore.
