Computational electrodynamics simulations provide a critical complement to experimental investigations for the understanding of light-matter interaction in complex systems. Its success is due in part to its relative simplicity and ease of use, couple

We report the use of Interferometric Second Harmonic Generation (I-SHG) microscopy to eliminate imaging artifacts from SHG patterns. Boundaries between two regions of opposite polarities in periodically-poled lithium niobate (PPLN) and in muscle myos

In this work, we report the implementation of interferometric second harmonic generation (SHG) microscopy with femtosecond pulses. As a proof of concept, we imaged the phase distribution of SHG signal from the complex collagen architecture of juvenil

Nonlinear optical imaging in the epi-direction is used to image subresolution features. We find that a refractive index mismatch between the object to be imaged and the background medium can change the far-field intensity image. As an example, we stu

Collagen ultrastructure plays a central role in the function of a wide range of connective tissues. Studying collagen structure at the microscopic scale is therefore of considerable interest to understand the mechanisms of tissue pathologies. Here, w

The nonlinear susceptibility phase is obtained by adapting ptychography to nonlinear optical microscopy. We develop a reconstructive technique to retrieve phase from far-field diffractive images, obtaining enhanced resolution despite distorted input

SRS and CARS microscopy images are distorted by near-field enhancements and microlensing depending on object shape, producing micron shifts in image position and up to an order of magnitude signal enhancement.

An inhomogeneous linear refractive index profile, such as that occurring in biological tissues, is shown to significantly alter stimulated Raman scattering (SRS) and coherent anti-Stokes Raman scattering (CARS) microscopy images. Our finite-differenc
