High-Q impurity photon states bounded by a photonic-band-pseudogap in an optically-thick photonic-crystal slab

Kavli Affiliate: Axel Scherer | First 5 Authors: Se-Heon Kim, Andrew Homyk, Sameer Walavalkar, Axel Scherer, | Summary: We show that, taking a two-dimensional photonic-crystal slab system as an example, surprisingly high quality factors (Q) over 10^5 are achievable, even in the absence of a rigorous photonic-band-gap. We find that the density of in-plane Bloch […]

Design and Construction of Absorption Cells for Precision Radial Velocities in the K Band using Methane Isotopologues

Kavli Affiliate: Nathan S. Lewis | First 5 Authors: Guillem Anglada-Escudé, Peter Plavchan, Sean Mills, Peter Gao, Edgardo García-Berríos | Summary: We present a method to optimize absorption cells for precise wavelength calibration in the near-infrared. We apply it to design and optimize methane isotopologue cells for precision radial velocity measurements in the K band. […]

Planar sheets meet negative curvature liquid interfaces

Kavli Affiliate: Mark Bowick | First 5 Authors: Zhenwei Yao, Mark Bowick, Xu Ma, Rastko Sknepnek, | Summary: If an inextensible thin sheet is adhered to a substrate with a negative Gaussian curvature it will experience stress due to geometric frustration. We analyze the consequences of such geometric frustration using analytic arguments and numerical simulations. […]

Technology developments for a scalable heterodyne MMIC array at W-band

Kavli Affiliate: Sarah Church | First 5 Authors: Matthew Sieth, Sarah Church, Judy M. Lau, Patricia Voll, Todd Gaier | Summary: We report on the development of W-band (75-110 GHz) heterodyne receiver technology for large-format astronomical arrays. The receiver system is designed to be both mass-producible, so that the designs could be scaled to thousands […]
