A SHARP view of H0LiCOW: H0 from three time-delay gravitational lens systems with adaptive optics imaging [PDF]
We present the measurement of the Hubble constant, H0, with three strong gravitational lens systems. We describe a blind analysis of both PG 1115+080 and HE 0435−1223 as well as an extension of our previous analysis of RXJ 1131−1231.

Ultrabroadband nonlinear optics in nanophotonic periodically poled lithium niobate waveguides [PDF]
Quasi-phasematched interactions in waveguides with quadratic nonlinearities enable highly efficient nonlinear frequency conversion. In this article, we demonstrate the first generation of devices that combine the dispersion-engineering available in ...

Metamaterial Coatings for Broadband Asymmetric Mirrors [PDF]
We report on design and fabrication of nano-composite metal-dielectric thin film coatings with high reflectance asymmetries. Applying basic dispersion engineering principles to model a broadband and large reflectance asymmetry, we obtain a model ...

Polarimetry with a soft x-ray spectrometer
An approach for measuring linear X-ray polarization over a broad-band using conventional spectroscopic optics is described. A set of multilayer-coated flats reflect the dispersed X-rays to the instrument detectors.

Dispersion-enabled quantum state control in integrated photonics
Integrated optics has brought unprecedented levels of stability and performance to quantum photonic circuits. However, integrated devices are not merely micron-scale equivalents of their bulk-optics counterparts.

Enhanced surface plasmon resonance absorption in metal-dielectric-metal layered microspheres
We present a theoretical study of the dispersion relation of surface plasmon resonances of mesoscopic metal-dielectric-metal microspheres. By analyzing the solutions to Maxwell's equations, we obtain a simple geometric condition for which the system ...
