The measured dispersion of a low-loss, hollow-core photonic band-gap fiber is anomalous
throughout most of the transmission band, and its variation with wavelength is large …

We present the first experimental demonstration of anomalous group-velocity dispersion
(GVD) in silicon waveguides across the telecommunication bands. We show that the GVD in …

Recent progress on numerical modeling methods for photonic crystal fibers (PCFs) such as
the effective index approach, basis-function expansion approach, and numerical approach …

We investigate strong light confinement in high core-cladding index contrast waveguides
with dimensions comparable to and smaller than the wavelength of incident light. We …

We demonstrate, for the first time to our knowledge, optical parametric oscillation based on
four-wave mixing in microstructure fiber. The measured wavelength-tunability range of the …

Ovarian cancer remains the most frequently lethal of the gynecologic cancers owing to the
late detection of this disease. Here, by using human specimens and three mouse models of …

We show that optical waveguides with sub-wavelength transverse dimensions optimize the
effective nonlinearity and provide desireable dispersive properties for generating …

We present a source of correlated photon pairs that relies on spontaneous parametric
scattering in microstructure fiber. Quantum correlations are shown between photon pairs that …

Using a full-vector finite-element method, we calculate birefringence and dispersion in index-
guiding photonic crystal fibers, also called holey fibers. Through real-model simulations the …
