  We review the potential of Astrophotonics, a relatively young field at the
interface between photonics and astronomical instrumentation, for
spectro-interferometry. We review some fundamental aspects of photonic science
that drove the emer- gence of astrophotonics, and highlight the achievements in
observational astrophysics. We analyze the prospects for further technological
development also considering the potential synergies with other fields of
physics (e.g. non-linear optics in condensed matter physics). We also stress
the central role of fiber optics in routing and transporting light, delivering
complex filters, or interfacing instruments and telescopes, more specifically
in the context of a growing usage of adaptive optics.
