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…
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…
2023 Astrophotonics Roadmap: pathways to realizing multi-functional integrated astrophotonic instruments
Nemanja Jovanovic, Pradip Gatkine, Narsireddy Anugu +77
Photonics offer numerous functionalities that can be used to realize astrophotonic instruments. The most spectacular example to date is the ESO Gravity instrument at the Very Large…
Optimal SMF packing in photonic lanterns: comparing theoretical topology to practical packing arrangements
John J. Davenport, Momen Diab, Kalaga Madhav +1
Photonic lanterns rely on a close packed arrangement of single mode fibers, which are tapered and fused into one multi-mode core. Topologically optimal circle packing arrangements…
Simulations of mode-selective photonic lanterns for efficient coupling of starlight into the single-mode regime
Momen Diab, Aashana Tripathi, John Davenport +3
In ground-based astronomy, starlight distorted by the atmosphere couples poorly into single-mode waveguides but a correction by adaptive optics, even if only partial, can boost cou…
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…
Modal analysis using photonic lanterns coupled to arrays of waveguides
Momen Diab, Stefano Minardi
We present a new concept of an integrated optics component capable of measuring the complex amplitudes of the modes at the tip of a multimode waveguide. The device uses a photonic…
