Predicting seizure freedom in the postpartum period: Findings from the Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs study

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to evaluate whether seizure freedom in pregnancy predicts seizure freedom in the postpartum period in women with epilepsy (WWE). Prior studies have shown that seizure freedom prior to conception strongly predicts seizure freedom during pregnancy.

Optical solitons with differential group delay for complex Ginzburg–Landau equation

Results in Physics, 2020
This paper addresses optical solitons in birefringent fibers that is modeled by complex Ginzburg–Landau equation with Kerr law nonlinearity. Three forms of integration architecture retrieves soliton and other solutions to the model.

Hybrid microspheres for nonlinear Kerr switching devices

Optics Express, 2011
Electronic Kerr effect in a polyfluorene derivative is used to reversibly switch near infrared probe beam resonantly coupled to a hybrid polymer-silica microspherical resonator. NIR pumping at 780 nm in pulsed laser regime is used for non-linear switching of the WGM resonances that shift as much as 2 GHz for 50 mW of average pump power, compared to a ...

Large Kerr nonlinearity in PdS2 2D films

, 2020
We report a large third-order nonlinear optical response of palladium diselenide (PdSe 2 ) films – a two-dimensional (2D) noble metal dichalcogenide material. Both open-aperture (OA) and closed-aperture (CA) Z-scan measurements are performed with a femtosecond pulsed laser at 800 nm to investigate ...

Efficient First‐Principles Inverse Design of Nanolasers

Laser &Photonics Reviews, EarlyView.
This article introduces a first‐principles inverse‐design framework for nanolasers that directly incorporates nonlinear lasing physics. By unifying steady‐state ab‐initio laser theory (SALT) with topology optimization, it reveals how spatial hole burning, gain saturation, and cavity‐emitter coupling shape laser performance, enabling efficient discovery

Germanium‐Based Mid‐Infrared Integrated Photonics

Laser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

A Modified Nonlinear Lorentz Model for Third-Order Optical Nonlinearity

Mathematics
In this study, we propose a new nonlinear polarization model that modifies the polarization equation to account for the material’s nonlinear response. Specifically, the nonlinear restoring force in our model is reformulated as an electric field-dependent
