Photonic technologies 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 Telescope in Chile that combines the light-gathering powe

Testbed for coupling starlight into fibers and astrophotonic instruments
Autor: Momen Diab, Kalaga Madhav, Martin Roth, Aline N. Dinkelaker, John J. Davenport
Publikováno v: Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation IV.
We assembled a testbed to study coupling of starlight through atmospheric turbulence via astronomical telescopes into astrophotonic devices. The setup allows for varying the turbulence strength and investigating the effects of different levels of ada

Starlight coupling through atmospheric turbulence into few-mode fibers and photonic lanterns in the presence of partial adaptive optics correction
Autor: Martin Roth, Kalaga Madhav, Momen Diab, John J. Davenport, Aline N. Dinkelaker
Starlight corrupted by atmospheric turbulence cannot couple efficiently into astronomical instruments based on integrated optics as they require light of high spatial coherence to couple into their single-mode waveguides. Low-order adaptive optics in

Photonic lanterns: a practical guide to filament tapering
Autor: Pranab J. Deka, Momen Diab, Kalaga Madhav, Aashana Tripathi, John J. Davenport, Martin Roth
Publikováno v: Optical Materials Express. 11:2639
We present a detailed method of tapering and drawing photonic lanterns using a filament glass processing system. Single-mode fibers (SMFs) were stacked inside a low refractive index, fluorine-doped capillary, which was then heated and tapered to prod

We will review the development in the last decade of discrete beam combiners (DBC), phase sensors based on the propagation of light in photonic lattices. The latest results on the development of DBC for astronomical applications will be presented, al

Simulations of mode-selective photonic lanterns for efficient coupling of starlight into the single-mode regime
Autor: Momen Diab, Kalaga Madhav, John J. Davenport, Martin Roth, Aline N. Dinkelaker, Aashana Tripathi
Publikováno v: Applied Optics. 60:D9
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 coupling into the few-mode regime allowing the use of photonic lanterns t

On the modal throughput of photonic lanterns in the presence of partial adaptive optic correction
Autor: Momen Diab, Stefano Minardi
Publikováno v: Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation III.
As compared to single-mode fibers (SMFs), photonic lanterns could ease the coupling of starlight to single-mode astrophotonic instruments. Here we investigate numerically the advantage of using lanterns as compared to SMFs for seeing-limited and low-

Modal analysis using photonic lanterns coupled to arrays of waveguides
Autor: Momen Diab, Stefano Minardi
Publikováno v: Optics Letters. 44:1718
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 lantern to split the optical power carried by an $N$-modes waveguide a
