Broadband spectral shaping using nematic liquid crystal
Results in Physics, 2019 We demonstrate what is, to our knowledge, the first implementation of nematic liquid crystal (LC) for spectral shaping of broadband light fields. A LC cell of several microns thickness is placed between a polarizer and an analyzer.

Multiplexed Bio‐detection on an Interferometric Optical Waveguide Assembly
Advanced Materials Interfaces, EarlyView.Multiplexed remote bio‐detection is demonstrated through an image conduit composed of 3012 individual cores and coated with interferometric layers. The proof of concept of biodetection is performed through the kinetic monitoring of two complementary DNA strands hybridization paving the way for applications in multiplex in situ biosensing, and ...

Phase retrieval from carrier frequency interferograms: reduction of the impact of space-variant disturbances [PDF]
Journal of the European Optical Society-Rapid Publications, 2015 Phase “extraction” by using temporal phase shifting is sensitive to vibrations and drifts, producing systematic phase errors periodic withtwice the fringe frequency.

, 2017 Matter-wave interferometry is a direct test of the quantum superposition principle for massive systems, and of collapse models. Here we show that the bounds placed by matter-wave interferometry depend weakly on the details of the collapse mechanism ...

Dynamical Imaging with Interferometry [PDF]
The Astrophysical Journal, 2017 Abstract By linking widely separated radio dishes, the technique of very long baseline interferometry (VLBI) can greatly enhance angular resolution in radio astronomy. However, at any given moment, a VLBI array only sparsely samples the information necessary to form an image.
