Starlight on a chip: astrophotonic technologies for interferometry
Optical and Infrared Interferometry and Imaging VII, 2020The impact photonic technologies have had, and continue to have, on astronomical interferometry are considerable and wide-ranging. Microscopic waveguide structures that coherently rout starlight are combined with other photonic components into `photonic chips', which can perform a myriad of functions useful to interferometry, such as beam combination ...

Towards Integrated Astrophotonic Instruments for Exoplanet Biosignature Detection
14th Pacific Rim Conference on Lasers and Electro-Optics (CLEO PR 2020), 2020We present the design of integrated astrophotonic instruments for high background atmospheric gas detection. Such instruments can be fibre-coupled to long focal length space telescopes as compact, flexure-free, instruments.

3D astrophotonic tricouplers for nulling interferometry
2023Nulling interferometry was first proposed back in the 1970’s and has since proven to be a promising technique for imaging exoplanets, overcoming the contrast and angular resolution limitations of single telescopes. This technique, implemented inside an integrated optical circuit, is used by the Guided Light Interferometric Nulling Technology (GLINT ...
