Performance limits of astronomical arrayed waveguide gratings on silica platform
Andreas Stoll, Kalaga Madhav, Martin Roth
We present a numerical and experimental study of the impact of phase errors on the performance of large, high-resolution Arrayed Waveguide Gratings (AWG) for applications in astron…
Starlight coupling through atmospheric turbulence into few-mode fibers and photonic lanterns in the presence of partial adaptive optics correction
Momen Diab, Aline N. Dinkelaker, John Davenport +2
Starlight corrupted by atmospheric turbulence cannot couple efficiently into astronomical instruments based on integrated optics as they require light of high spatial coherence to…
Complex phase masks for fabricating OH-suppression filters for astronomy
Aashia Rahman, Kalaga Madhav, Martin M. Roth
The design of a complex phase mask (CPM) for inscribing aperiodic filters in fibers is presented. The complex structure of the mask surface relief consists of discrete aperiodic ph…
First demonstration of OH suppression in a high efficiency near-infrared spectrograph
S. C. Ellis, J. Bland-Hawthorn, J. S. Lawrence +21
Ground-based near-infrared astronomy is severely hampered by the forest of atmospheric emission lines resulting from the rovibrational decay of OH molecules in the upper atmosphere…
