Thirty years ago, Coullet et al. proposed that a special optical field exists in laser cavities
bearing some analogy with the superfluid vortex. Since then, optical vortices have been …

The geometric phase concept has profound implications in many branches of physics, from
condensed matter physics to quantum systems. Although geometric phase has a long …

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

" This engagingly written text provides a useful pedagogical introduction to an extensive
class of geometrical phenomena in the optics of polarization and phase, including simple …

In this paper, we review the impact of small sample statistics on detection thresholds and
corresponding confidence levels (CLs) in high-contrast imaging at small angles. When …

Observations of circumstellar environments that look for the direct signal of exoplanets and
the scattered light from disks have significant instrumental implications. In the past 15 years …

HCIPy is a package written in Python for simulating the interplay between wavefront control
and coronagraphic systems. By defining an element which merges values/coefficients with …

We experimentally and numerically tested the separability of two independent equally
luminous mono<? format?> chromatic and white light sources at the diffraction limit, using …

Many high-contrast coronagraph designs have recently been proposed. In this paper, their
suitability for direct imaging of extrasolar terrestrial planets is reviewed. We also develop a …

A direct image of an exoplanet system is a snapshot of the planets and disk around a central
star. We can estimate the orbit of a planet from a time series of images, and we can estimate …
