Modal noise in an integrated photonic lantern fed diffraction-limited spectrograph
N. Cvetojevic, N. Jovanovic, S. Gross +9
In an attempt to develop a streamlined astrophotonic instrument, we demonstrate the realization of an all-photonic device capable of both multimode to single mode conversion and sp…
Efficient photonic reformatting of celestial light for diffraction-limited spectroscopy
David G. MacLachlan, Robert J. Harris, Itandehui Gris-Sánchez +9
The spectral resolution of a dispersive astronomical spectrograph is limited by the trade-off between throughput and the width of the entrance slit. Photonic guided-wave transition…
Integrated photonic building blocks for next-generation astronomical instrumentation II: the multimode to single mode transition
Izabela Spaleniak, Nemanja Jovanovic, Simon Gross +3
There are numerous advantages to exploiting diffraction-limited instrumentation at astronomical observatories, which include smaller footprints, less mechanical and thermal instabi…
Multiband processing of multimode light: combining 3D photonic lanterns with waveguide Bragg gratings
Izabela Spaleniak, Simon Gross, Nemanja Jovanovic +4
The first demonstration of narrowband spectral filtering of multimode light on a 3D integrated photonic chip using photonic lanterns and waveguide Bragg gratings is reported. The p…
Integrated photonic building blocks for next-generation astronomical instrumentation I: the multimode waveguide
Nemanja Jovanovic, Izabela Spaleniak, Simon Gross +5
We report on the fabrication and characterization of composite multimode waveguide structures that consist of a stack of single-mode waveguides fabricated by ultrafast laser inscri…
