Journal ArticleDOI
Fundamental electro-optic limitations of thin-film lithium niobate microring modulators.
TL;DR: This work investigates the impact of waveguide curvature on the electro-optic efficiency of microring resonators in thin-film X-cut or Y-cut lithium niobate (in-plane extraordinary axis) and derives explicit relations on the response and shows that this limitation does not exist and can be circumvented.
Journal ArticleDOI
Regularized pseudo-phase imaging for inspecting and sensing nanoscale features.
TL;DR: This article introduces the regularized pseudo-phase, an observation quantity for polychromatic visible light microscopy that seems to be more sensitive than conventional intensity images for characterizing nanoscale features and achieves a significant improvement in signal to noise ratio without making any changes to the imaging hardware.
Journal ArticleDOI
Ultra-efficient and fully isotropic monolithic microring modulators in a thin-film lithium niobate photonics platform
TL;DR: A symmetric electrode configuration is presented to boost the vertical field strength inside a fully-etched single-mode LN waveguide to demonstrate an ultra-compact fully isotropic microring modulator with a high electro-optic tuning efficiency, extinction ratio of 20 dB, and modulation bandwidth beyond 28 GHz.
Journal ArticleDOI
Quantitative phase imaging of weakly scattering objects using partially coherent illumination.
TL;DR: This paper derived a mathematical framework that provides an intuitive model of image formation under varying degrees of coherence and provides a clear connection between the halo effect and phase underestimation, defocusing and the 3D structure of the sample under investigation.
Journal ArticleDOI

TL;DR: In this article, the gain lever parameter space has been fully characterized and validated against numerical simulations of a semi-3-D hybrid beam propagation method (BPM) model for the coupled electron-photon rate equation.
