The JWST NIRSpec integral field unit (IFU) presents a unique opportunity to observe directly
imaged exoplanets from 3 to 5 μm at moderate spectral resolution (R∼ 2700) and thereby …

Astrophotonics represents a cutting-edge approach in observational astronomy. This paper
explores the significant advancements and potential applications of astrophotonics …

Vortex fiber nulling (VFN) is a technique for detecting and characterizing faint companions at
small separations from their host star. A near-infrared (∼ 2.3 μm) VFN demonstrator mode …

We summarize the current best polychromatic (∼ 10% to 20% bandwidth) contrast
performance demonstrated in the laboratory by different starlight suppression approaches …

Discovering exoplanets in orbit around distant stars via direct imaging is fundamentally
impeded by the high dynamic range between the star and the planet. Coronagraphs strive to …

KPIC (the Keck Planet Imager and Characterizer) is a series of upgrades for the Keck II
Adaptive Optics system and the NIRSPEC spectrograph to enable diffraction-limited, high …

Broadband low-resolution near-infrared spectrographs in a compact form are crucial for
ground-and space-based astronomy and other fields of sensing. Astronomical spectroscopy …

Exoplanets can be detected very close to stars using single-mode cross-aperture nulling
interferometry, a photonic technique that relies on the inability of an anti-symmetric stellar …

The use of a photonic lantern as focal plane wavefront sensor has seen recent widespread
interest–it can remove non-common-path aberrations, accurately sense low-wind-effect and …

Photonic lantern nulling (PLN) is a method for enabling the detection and characterization of
close-in exoplanets by exploiting the symmetries of the ports of a mode-selective photonic …
