Description As a result of this award, we have identified a number of ways in which photonics technology can be used to improve astronomical instrumentation. This includes ways to use a combination of multi-core fibre optics, photonic lanterns and laser-written waveguides to reduce or eliminate various sources of noise in high-resolution spectrographs, and implement new types of integral field units.
Exploitation Route The outcomes might be used as the basis for new instruments for astronomical telescopes, or indeed anywhere where a need for high-resolution spectroscopy is combined with the use of optical fibres.

Title Data for "Diffraction-limited integral-field spectroscopy for extreme adaptive-optics systems with the Multi-Core fiber-fed Integral-Field Unit" 
Description Direct imaging instruments have the spatial resolution to resolve exoplanets from their host star. This enables direct characterization of the exoplanet's atmosphere, but most direct imaging instruments do not have spectrographs with high enough spectral resolving power for detailed atmospheric characterization. We used recent advances in photonic manufacturing to create the Multi-Core fiber-fed Integral-Field Unit (MCIFU), a novel integral-field spectrograph for telescopes that have adaptive optics systems. The data set is a collection of data files from the MCIFU project that were used to validate and measure the performance of the MCIFU, both in the lab and on-sky. The on-sky data was taken with the adaptive optics instrument CANARY at the 4.2m William Herschel Telescope on the Canary Islands in July 2019. The data that is collected here was used to create the figures in the draft "Diffraction-limited integral-field spectroscopy for extreme adaptive optics systems with the Multi-Core fiber-fed Integral-Field Unit" that is under review in JATIS.For inquiries regarding the contents of this dataset, please contact the Corresponding Author listed in the README.txt file.

Title Dataset for "An endlessly adiabatic fibre with a logarithmic refractive index distribution" 
Description This dataset contains the data underlying the results reported in K. Harrington et al., "An endlessly adiabatic fibre with a logarithmic refractive index distribution". The data includes the results of calculations and measurements of a fibre with a novel refractive index distribution. This includes calculated mode field diameters for various outer diameters of the fibre. Also included are optical micrographs and near-field images recorded by digital sensors and stress distributions for fibres made with different drawing conditions.
