Applications of Integrated Photonic Spectrographs in Astronomy
Robert James Harris, Jeremy Allington-Smith
One of the problems of producing instruments for Extremely Large Telescopes is that their size (and hence cost) scales rapidly with telescope aperture. To try to break this relatio…
Simulation of complex phenomena in optical fibres
Jeremy Allington-Smith, Graham Murray, Ulrike Lemke
Optical fibres are essential for many types of highly-multiplexed and precision spectroscopy. The success of the new generation of multifibre instruments under construction to inve…
Ultrafast Laser Inscription of a 121-Waveguide Fan-Out for Astrophotonics
R. R. Thomson, R. J. Harris, T. A. Birks +3
Using ultrafast laser inscription, we report the fabrication of a prototype three-dimensional 121-waveguide fan-out device capable of reformatting the output of a 120 core multicor…
