Abstract: Astrophotonics lies at the interface of photonics and astronomical instrumentation. Its goal is to manipulate light in new ways to enable new kinds of astronomical science or to undertake traditional astronomy in more effective ways. In other words, its aim is to achieve more, or to achieve more with less. In recent years, we have begun to feed light efficiently from large telescopes into photonic devices via photonic lanterns or/and an AO systems. This opens a largely unchartered landscape rich with possibilities. Photonic devices have the additional advantage of mass replication, low power requirements, robustness, small footprint and minimal weight. The power of photonics and gradual improvements in AO at most observatories, together with the development of new photonic devices, strengthens the case for astrophotonics year by year.
