Near-field to far-field transition of photonic crystal fibers: symmetries and interference phenomena
Niels Asger Mortensen, Jacob Riis Folkenberg
The transition from the near to the far field of the fundamental mode radiating out of a photonic crystal fiber is investigated experimentally and theoretically. It is observed tha…
Effective area of photonic crystal fibers
Niels Asger Mortensen
We consider the effective area A_eff of photonic crystal fibers (PCFs) with a triangular air-hole lattice in the cladding. It is first of all an important quantity in the context o…
Numerical Aperture of Single-Mode Photonic Crystal Fibers
N. A. Mortensen, J. R. Folkenberg, P. M. W. Skovgaard +1
We consider the problem of radiation into free space from the end-facet of a single-mode photonic crystal fiber (PCF). We calculate the numerical aperture NA=sin theta from the hal…
