Initial modeling and testbed feasibility studies of WaveDriver: a laser guide star AO system for HWO
Dominic F. Sanchez, Benjamin L. Gerard, Peter Waswa +16
The Habitable Worlds Observatory (HWO) will require greater wavefront stability than achieved by JWST, pushing conventional telescope architectures to picometer-level…

Laboratory characterization of a multi-photonic lantern optical waveguide using off-axis holography
Aditya R. Sengupta, Benjamin L. Gerard, Dominic Sanchez +7
Photonic lanterns (PLs) are waveguides that convert multi-mode input light to single-mode outputs. Wavefront sensing (WFS) and spectroscopy using a PL have been demonstrated, but P…

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…
