Evanescent coupling from optical fiber tapers to photonic crystal waveguides and resonators [PDF]

open access: green, 2003
Using a coupled mode theory and finite-difference time-domain calculations nearly complete evanescent power transfer between a fiber taper and a photonic crystal defect waveguide which is ideal for probing high-Q cavities is ...

Optical fiber-based measurement of ultra-small mode volume and a high quality factor in a photonic crystal microcavity [PDF]

open access: green, 2004
Using an optical fiber taper that simultaneously probes the spectral and spatial properties of resonant cavity modes, two-dimensional Si photonic crystal microcavities with a quality factor Q~40,000 and modal volume V_eff ~0.9(λ/n)^3 are experimentally ...

Hydrophobic photonic crystal fibers [PDF]

open access: yesOptics Letters, 2011
We propose and demonstrate hydrophobic photonic crystal fibers (PCFs). A chemical surface treatment for making PCFs hydrophobic is introduced. This repels water from the holes of PCFs, so that their optical properties remain unchanged even when they are immersed in water.
