Characterization of 1D photonic crystal nanobeam cavities using curved microfiber [PDF]

, 2010
We investigate high-Q, small mode volume photonic crystal nanobeam cavities using a curved, tapered optical microfiber loop. The strength of the coupling between the cavity and the microfiber loop is shown to depend on the contact position on the ...

Vortex solitons in photonic crystal fibers

, 2003
We demonstrate the existence of vortex soliton solutions in photonic crystal fibers. We analyze the role played by the photonic crystal fiber defect in the generation of optical vortices.
