Sub millimetre flexible fibre probe for background and fluorescence free Raman spectroscopy
Stephanos Yerolatsitis, András Kufcsák, Katjana Ehrlich +11
Using the shifted-excitation Raman difference spectroscopy technique and an optical fibre featuring a negative curvature excitation core and a coaxial ring of high numerical apertu…
Diffraction-limited integral-field spectroscopy for extreme adaptive optics systems with the Multi-Core fiber-fed Integral-Field Unit
Sebastiaan Y. Haffert, Robert J. Harris, Alessio Zanutta +31
Direct imaging instruments have the spatial resolution to resolve exoplanets from their host star. This enables direct characterization of the exoplanets atmosphere, but most direc…
Focal-ratio-degradation (FRD) mitigation in a multimode fiber link using mode-selective photonic lanterns
Aurélien Benoît, Stephanos Yerolatsitis, Kerrianne Harrington +2
We present a new way to mitigate focal-ratio degradation (FRD) when using optical fibers to transport multimode light. Our approach exploits a custom multicore fiber (MCF) with six…
Modal noise mitigation for high-precision spectroscopy using a photonic reformatter
Fraser A. Pike, Aurélien Benoît, David G. MacLachlan +5
Recently, we demonstrated how an astrophotonic light reformatting device, based on a multicore fibre photonic lantern and a three-dimensional waveguide component, can be used to ef…
