All-Fiber Broadband Wavelength-Division Multiplexing using Heterogeneous Photonic Lanterns
Abani Shankar Nayak, Julius Goehring, Martin M. Roth +1
This work presents an all-fiber broadband wavelength-division multiplexing architecture using 1x7 heterogeneous photonic lanterns (PLs), specifically PL-(6+1) and PL-(4+3). By comb…
Commissioning the AIP's ultrafast laser Inscription facility: defining the parameter space for type-I waveguide fabrication
Rima Islam, Aline N. Dinkelaker, Abani Shankar Nayak +2
Astrophotonics offers a compact, stable alternative to bulk optics in traditional astronomical instrumentation, spanning high-precision spectroscopy to high-contrast interferometry…
Sensing ELT petal modes with a discrete beam combiner: an end-to-end theoretical model
Kalaga V. Madhav, Abani Shankar Nayak, Lucas Labadie +1
The European Southern Observatory's Extremely Large Telescope (ELT), the 39-m telescope under construction in Chile, forms its entrance pupil from 798 hexagonal segments that the s…
Towards High-Throughput Visible Photonic Lanterns for the EMARCOT Project
Abani Shankar Nayak, Julius Goehring, Marina Centenera-Merino +14
Photonic EMARCOT is an innovative project involving Spanish, German and Australian research institutes that aims to integrate multiple Optical Tube Assemblies (OTAs) using photonic…
Demonstration of a multimode-to-multimode photonic lantern for astronomy
Marina Centenera-Merino, Andrew Ross-Adams, Christopher Betters +14
Photonic lanterns have been widely used in astronomy as low-loss multiplexing devices, typically coupling light from a multimode input into several single-mode outputs. In this wor…
Comparative analysis of fiber Bragg grating filter losses inscribed by continuous wave UV and femtosecond-IR lasers for astrophotonics
Aashia Rahman, Ria G. Krämer, Abani Shankar Nayak +8
Fiber Bragg grating (FBG) filters have been demonstrated as promising components in astrophotonic instrumentation for near-infrared ground-based observations. Given the photon-star…
Towards a Comprehensive Understanding of Planetary Systems through Population-Level, Large-Scale Surveys
Francisco J. Pozuelos, Pedro J. Amado, Jesús Aceituno +13
Over the past three decades, exoplanet research has delivered an extensive census of planets spanning a wide range of masses, sizes, and orbital configurations. Despite this progre…
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…
Six-telescope integrated optics beam combiner fabricated using ultrafast laser inscription for J- and H-band astronomy
Aline N. Dinkelaker, Sebastian Smarzyk, Abani S. Nayak +6
We have built and characterized the first six-telescope discrete beam combiner (DBC) for stellar interferometry in the astronomical J-band. It is the DBC with the largest number of…
