Protecting superconducting qubits from phonon mediated decay
Autor: Tiziana C. Bond, S. E. Harrison, Eric Holland, Jonathan L. DuBois, Matthew A. Horsley, Yaniv Rosen, Allan S. P. Chang
For quantum computing to become fault tolerant, the underlying quantum bits must be effectively isolated from the noisy environment. It is well known that including an electromagnetic bandgap around the qubit operating frequency improves coherence fo

Autor: Mihail Bora, Benjamin J. Fasenfest, Elaine M. Behymer, Allan S-P Chang, Hoang T. Nguyen, Jerald A. Britten, Cindy C. Larson, James W. Chan, Robin R. Miles, Tiziana C. Bond
Publikováno v: Nano Letters. 10:2832-2837
Tunable plasmon resonant cavity arrays in paired parallel nanowire waveguides are presented. Resonances can be observed when the waveguide length is an odd multiple of quarter plasmon wavelengths, consistent with boundary conditions of node and antin

We report a chemical-wet-etching patterned-sapphire-substrate (CWE-PSS) that simultaneously enhances internal quantum efficiency and light extraction efficiency of gallium nitride based light-emitting-diode (LED). According to transmission electron m

Publikováno v: Journal of Physics D: Applied Physics. 40:2624-2628
Three-dimensional (3D) Si spiral photonic crystals have been realized by oblique angle deposition with a new approach of substrate 'swing' rotation. We demonstrate that, by using swing rotation, the arms of the spirals can be grown with a uniform dia

In this paper the experimental results show near-infrared light collimation through large area (2 x 2 mm) nanopatterned material with refractive index quasi-zero on the average. This quasi-zero refractive index is obtained alternating photonic crysta

Inspired by the concept of complementary media, we experimentally demonstrate that an engineered metamaterial made of alternating, stripe layers of negatively refracting (photonic crystals) and positively refracting (air) materials strongly collimate

Physical origin of the resonant mode deep inside the stop band of a metallodielectric photonic crystal
Autor: Minfeng Chen, Allan S. P. Chang, Shawn-Yu Lin, Hung-chun Chang
Publikováno v: Physical Review B. 78
The first band of a typical layer-by-layer metallodielectric woodpile structure corresponds to the waveguide cutoff of the rod-to-rod opening. However, a nonlocalized propagating mode beyond waveguide cutoff was previously observed if the metallic gr

We investigate a plasmonic resonant structure tunable from ultra-violet to near infrared wavelengths with maximum absorbance strength over 95% due to a highly efficient coupling with incident light. Additional harmonics are excited at higher frequenc

Publikováno v: Applied Physics Letters. 97:113701
The defect-free photonic crystal (PC) slab geometry was explored for size-selective detection of bio-organism simulants. Through feedback between finite-difference time-domain simulations and experiments, we generated a conservative limit of detectio
