Experimental demonstration of photonic phase correctors based on grating coupler arrays and thermo-optic shifters
Momen Diab, Ross Cheriton, Jacob Taylor +9
In ground-based astronomy, the ability to couple light into single-mode fibers (SMFs) is limited by atmospheric turbulence, which prohibits the use of many astrophotonic instrument…
Astrophotonic Solutions for Spectral Cross-Correlation Techniques
Suresh Sivanandam, Ross Cheriton, Polina Zavyalova +7
Using photonic devices, we developed a new approach to traditional spectroscopy where the spectral cross-correlation with a template spectrum can be done entirely on-device. By cre…
Simultaneous estimation of segmented telescope phasing errors and non-common path aberrations from adaptive optics corrected images
Masen Lamb, Carlos Correia, Suresh Sivanandam +2
We investigate the focal plane wavefront sensing technique, known as Phase Diversity, at the scientific focal plane of a segmented mirror telescope with an adaptive optics (AO) sys…
