Performance estimation of photonic integrated wavefront corrector for single-mode fiber coupling
Dhwanil Patel, Momen Diab, Ross Cheriton +3
Many modern astronomical instruments rely on the optimal coupling of starlight into single-mode fibers (SMFs). For ground-based telescopes, this coupling is limited by atmospheric…
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…
Integrated astrophotonic phase control for high resolution optical interferometry
Ross Cheriton, Siegfried Janz, Glen Herriot +2
Long baseline optical interferometry and aperture synthesis using ground-based telescopes can enable unprecedented angular resolution astronomy in the optical domain. However, atmo…
End-to-end simulations of photonic phase correctors for adaptive optics systems
Dhwanil Patel, Momen Diab, Ross Cheriton +8
Optical beams and starlight distorted by atmospheric turbulence can be corrected with adaptive optics systems to enable efficient coupling into single-mode fibers. Deformable mirro…
