Efficient photonic reformatting of celestial light for diffraction-limited spectroscopy (2016)
Journal Article
MacLachlan, D., Harris, R., Gris-Sánchez, I., Morris, T., Choudhury, D., Gendron, E., …Thomson, R. (2017). Efficient photonic reformatting of celestial light for diffraction-limited spectroscopy. Monthly Notices of the Royal Astronomical Society, 464(4), 4950-4957. https://doi.org/10.1093/mnras/stw2558

The spectral resolution of a dispersive astronomical spectrograph is limited by the trade-off between throughput and the width of the entrance slit. Photonic guided wave transitions have been proposed as a route to bypass this trade-off, by enabling...

Development of integrated mode reformatting components for diffraction-limited spectroscopy (2015)
Journal Article
MacLachlan, D. G., Harris, R. J., Choudhury, D., Simmonds, R. D., Salter, P. S., Booth, M. J., …Thomson, R. R. (2016). Development of integrated mode reformatting components for diffraction-limited spectroscopy. Optics Letters, 41(1), 76-79. https://doi.org/10.1364/ol.41.000076

We present the results of our work on developing fully integrated devices (photonic dicers) for reformatting multimode light to a diffraction limited pseudo-slit. These devices can be used to couple a seeing limited telescope point spread function to...

Applications of Integrated Photonic Spectrographs in astronomy (2013)
Journal Article
Harris, R., & Allington-Smith, J. (2013). Applications of Integrated Photonic Spectrographs in astronomy. Monthly Notices of the Royal Astronomical Society, 428(4), 3139-3150. https://doi.org/10.1093/mnras/sts265

One of the problems of producing instruments for extremely large telescopes (ELTs) is that their size (and hence cost) scales rapidly with telescope aperture. To try to break this relation alternative new technologies have been proposed, such as the... Read More about Applications of Integrated Photonic Spectrographs in astronomy.
