The chalcogen glasses (ie, glasses based on the elements S, Se, and Te) are transparent in
the infrared (IR), possess low phonon energies, are chemically durable, and can be drawn …

The characterization of exoplanets is critical to understanding planet diversity and formation,
their atmospheric composition, and the potential for life. This endeavour is greatly enhanced …

Photonic technologies offer numerous functionalities that can be used to realize
astrophotonic instruments. The most spectacular example to date is the ESO Gravity …

Astrophotonics lies at the interface of astronomy and photonics. This burgeoning field has
emerged over the past decade in response to the increasing demands of astronomical …

Research activities during the last decade have shown the strong potential of photonic

Nulling interferometry enables astronomers to advance beyond the resolving power of
ground-based telescopes with the goal of directly detecting exo-planets. By diminishing the …

ABSTRACT The Palomar Fiber Nuller (PFN) is a rotating-baseline nulling interferometer that
enables high-accuracy near-infrared (NIR) nulling observations with full azimuth coverage …

The quest for other habitable worlds and the search for life among them are major goals of
modern astronomy. One way to make progress towards these goals is to obtain high-quality …

Space-based nulling interferometry is one of the most promising solutions to spectrally
characterize the atmosphere of rocky exoplanets in the mid-infrared (3 to 20 μm). It provides …

Nulling interferometers combine on-axis suppression with high angular resolution, making
them ideal instruments for the direct detection of faint planets close to their parent star …
