Light propagation and emission in complex photonic media [PDF]
, 2014 We provide an introduction to complex photonic media, that is, composite materials with spatial inhomogeneities that are distributed over length scales comparable to or smaller than the wavelength of light.

Rapid Generation of Light Beams Carrying Orbital Angular Momentum [PDF]
, 2013 We report a technique for encoding both amplitude and phase variations onto a laser beam using a single digital micro-mirror device (DMD). Using this technique, we generate Laguerre-Gaussian and vortex orbital-angular-momentum (OAM) modes, along with ...

Automatic Modal Wavefront Estimation and Correction for Optical Aberration
IEEE Photonics Journal, 2019 Modal estimation of aberration can quantify the amount of aberration, which plays an important role in optical system optimization, aberration correction, and so on. Here, we propose a simple but effective method to find the modal wavefront of aberration.

Correction of Distorted Wavefront Using Dual Liquid Crystal Spatial Light Modulators
Photonics, 2022 In space optical communication, owing to the influence of atmospheric turbulence, optical beams lose focus and become phase-distorted, which reduces the communication quality.
