Photonic lanterns are made by adiabatically merging several single-mode cores into one
multimode core. They provide low-loss interfaces between single-mode and multimode …

Multimode optical fibers have been primarily (and almost solely) used as “light pipes” in
short distance telecommunications and in remote and astronomical spectroscopy. The …

Adaptive optics (AO) is critical in astronomy, optical communications and remote sensing to
deal with the rapid blurring caused by the Earth's turbulent atmosphere. But current AO …

Extreme adaptive optics (AO) systems are now in operation across the globe. These
systems, capable of high order wavefront correction, deliver Strehl ratios of $\sim 90\% $ in …

There are numerous advantages to exploiting diffraction-limited instrumentation at
astronomical observatories, which include smaller footprints, less mechanical and thermal …

The spectral resolution of a dispersive spectrograph is dependent on the width of the
entrance slit. This means that astronomical spectrographs trade-off throughput with spectral …

We demonstrate for the first time an efficient, photonic-based astronomical spectrograph on
the 8-m Subaru Telescope. An extreme adaptive optics system is combined with pupil …

Since its emergence two decades ago, astrophotonics has found broad application in
scientific instruments at many institutions worldwide. The case for astrophotonics becomes …

Astrophotonics represents a cutting-edge approach in observational astronomy. This paper
explores the significant advancements and potential applications of astrophotonics …

The sensitivity advantage of waveguide-enhanced Raman spectroscopy (WERS) over free-
space Raman, measured by the signal-to-noise ratio, is well established for thin molecular …
