Integrated optics for astronomical interferometry [PDF]

open access: yesAstronomy and Astrophysics Supplement Series, 1999
We propose a new instrumental concept for long-baseline optical single-mode interferometry using integrated optics which were developed for telecommunication. Visible and infrared multi-aperture interferometry requires many optical functions (spatial filtering, beam combination, photometric calibration, polarization control) to detect astronomical ...

Introduction to the Special Issue on Structured Light Coherence

open access: yesPhotonics, 2021
Statistical optics, and optical coherence in particular, developed into a stand-alone branch of physical optics in the second half of the 20th century and has found a number of ground-breaking applications in astronomical measurements, medical ...

Dispersion Characteristics of the Multi-mode Fiber-fed VIPA Spectrograph

open access: yesThe Astronomical Journal, 2023
A high-resolution ( ${ \mathcal R }\gt {10}^{5}$ ), multi-mode fiber-fed spectrograph on large telescopes with a reasonable size is desirable in astronomy.

Chromatic response of a four-telescope integrated-optics discrete beam combiner at the astronomical L band.

open access: yesOptics Express, 2020
We show the results of simulation and experimental study of a 4-telescope zig-zag discrete beam combiner (DBC) for long-baseline stellar interferometry working at the astronomical L band (3 - 4 µm) under the influence of a narrow bandwidth light source ...

Generalized large optics fabrication multiplexing

open access: yesJournal of the European Optical Society-Rapid Publications, 2022
High precision astronomical optics are manufactured through deterministic computer controlled optical surfacing processes, such as subaperture small tool polishing, magnetorheological finishing, bonnet tool polishing, and ion beam figuring.
