On-sky demonstration of second-stage wavefront control with a photonic lantern
Aditya R. Sengupta, Jordan Diaz, Matthew DeMartino +14
Ground-based direct imaging of exoplanets at high contrast requires precise correction of atmospheric turbulence using adaptive optics (AO). The planet-to-star contrast ratio at sm…

Experimental validation of photonic lantern imaging and wavefront sensing performance
Aditya R. Sengupta, Vincent Chambouleyron, Jordan Diaz +15
Photonic lanterns (PLs) are fiber-based waveguides that are capable of focal-plane wavefront sensing while simultaneously directing light to downstream science instruments. The opt…
