Abstract
The efficiency of photon collection from a reconfigurable photonic crystal (PhC) resonator through a curved microfiber is investigated by means of k-space analyses. We observed that efficient photon collection through the microfiber can be achieved when the PhC slab is thinner than 0.6a, where a is the lattice constant of the PhC. For thicker slabs, loss through the slab TM mode, which stems from the broken mirror symmetry of the slab, becomes significant. It was found that this TM-mode coupling can be suppressed considerably by reducing the thickness of the slab.
