Three-dimensional quantitative phase imaging via tomographic deconvolution phase microscopy
TL;DR: A new phase reconstruction method, called tomographic deconvolution phase microscopy (TDPM), is described which makes use of commercial microscopy hardware in realizing 3D QPI and is based on the 3D weak object transfer function theory, shown here to be capable of imaging "nonweak" phase objects with large phase excursions.
Journal ArticleDOI
Hollow waveguides with low intrinsic photoluminescence fabricated with Ta2O5 and SiO2 films
Yue Zhao,Micah H. Jenkins,Philip Measor,Kaelyn D. Leake,Shuo Liu,Holger Schmidt,Aaron R. Hawkins +6 more
TL;DR: Hollow core waveguides made with a combination of plasma-enhanced chemical vapor deposition SiO( 2) and sputtered Ta(2)O(5) provide a nearly optimal structure for optofluidic biofluorescence measurements with low optical loss, high fabrication yield, and low background photoluminescence.
Journal ArticleDOI
Quantitative phase microscopy via optimized inversion of the phase optical transfer function.
TL;DR: A new defocus-based reconstruction method that utilizes a small number of efficiently sampled micrographs to optimally invert the partially coherent phase optical transfer function under assumptions of weak absorption and slowly varying phase is described.
Journal ArticleDOI
Multifilter phase imaging with partially coherent light
TL;DR: A novel quantitative phase imaging method is shown to estimate phase accurately over a wide range of length scales using Köhler illumination from an extended incoherent source using multiple Savitzky-Golay differentiation filters.

TL;DR: In this paper, a broadband phase shifter based on Brillouin scattering in a suspended silicon waveguide is proposed, achieving a full 360° phase shift over a bandwidth of 15 GHz using a phase enhancement factor of 25.
