All-fibre wavefront sensor
Thomas A. Wright, Stephanos Yerolatsitis, Kerrianne Harrington +2
We report on a tapered three-core optical fibre that can be used as a tip-tilt wavefront sensor. In this device, a coupled region of a few millimetres at the sensing tip of the fib…
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…
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…
The Photonic Lantern
T. A. Birks, I. Gris-Sánchez, S. Yerolatsitis +2
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 systems wh…
