Abstrakt

Large mode area (LMA), single-mode photonic crystal fibres (PCFs) have the potential to provide significant instrumental advantages in fibre stellar interferometry, due to their broadband attenuation spectrum, endlessly single-moded performance and very large core size. We investigate the theoretical performance of coupling the telescope point spread function directly into LMA PCFs. We find that a single LMA fibre can replace as many as three step-index fibres for atmospheric seeing characterized by D-T/r(o) >= 2 with approximately the same coupling performance and a slower feed from the telescope. This could lead to considerable simplification of broad-band fibre interferometers.
