Why we need itWhy we need it
• Main themes for astronomy– Equation of state of the universe– Galactic archaelogy – Extrasolar planets; AGN studies
→ large aperture and high spatial resolution → ELTs → very high spatial resolution → LBOIRI
AstroPhotonics AstroPhotonics can bring major benefits to:can bring major benefits to:
– Highly-multiplexed spectroscopy – a critical technique -
– Specific technical problems for ELTs to be solved– Improved utility of long-baseline opt/IR interferometry– Pre-dispersion removal of telluric background

What actually is photonics?What actually is photonics?
The behaviour of a medium The behaviour of a medium depends not only on the depends not only on the type of its constituent type of its constituent atoms but also on the atoms but also on the geometrical layout of the geometrical layout of the atomic oscillatorsatomic oscillators
