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 to convert into multiple single-mode beams. Corrected wavefronts result in focal patterns that couple mostly with circularly symmetric waveguide modes. A mode-selective photonic lantern is hence proposed to convert multimode light into a subset of…

Astrophotonics: introduction to the feature issue

This introduction provides a summary of the papers that cover several important topics, such as photonic lanterns, beam combiners and interferometry, spectrographs, OH suppression, and coronagraphy, in the joint issue of JOSA B and Applied Optics.



Starlight coupling through atmospheric turbulence into few-mode fibres and photonic lanterns in the presence of partial adaptive optics correction

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

Photonic lanterns: a study of light propagation in multimode to single-mode converters.

The modal behaviour of photonic lanterns as well as the conditions for achieving low-loss between a multimode fibre and a "near-diffraction limited" single-mode system are evaluated.

Modal analysis using photonic lanterns coupled to arrays of waveguides.

A new concept of an integrated optics component capable of measuring the complex amplitudes of the modes at the tip of a multimode waveguide is presented and its application to the real-time measurement of modal instability in high power fiber lasers is proposed.

Geometric requirements for photonic lanterns in space division multiplexing.

This work uses modal analysis, the beam propagation method, and a transfer matrix technique to analyze the lanterns throughput along with its mode dependent loss and shows that unitary coupling between single-mode fibers and a multi-mode fiber is only possible by optimizing the arrangements of the cores.

Design of highly mode group selective photonic lanterns with geometric optimization.

It is demonstrated that mode group selectivity can be greatly improved by optimizing core geometry of PLs with optimized core geometry, based on beam propagation method (BPM) simulation results.

Bending sensor combining multicore fiber with a mode-selective photonic lantern.

A bending sensor is demonstrated using the combination of a mode-selective photonic lantern (PL) and a multicore fiber, which reveals a high sensitivity to bending curvature and differential power distributions according to bending direction, without the need for spectral measurements.

A focal-ratio-degradation resistant multimode fiber link using mode-selective photonic lantern

We report a new route to mitigate focal-ratio degradation (FRD) in multimode optical fiber links. Our approach uses a custom multicore fiber (MCF) with dissimilar cores, which is then tapered at both
