Journal ArticleDOI
Fabrication and characterization of narrow-band Bragg-reflection filters in silicon-on-insulator ridge waveguides
TL;DR: In this paper, the authors describe the design, fabrication and measurement of an integrated-optical Bragg filter, operating at a freespace wavelength of 1543 nm, based upon a silicon-on-insulator (SOI) ridge waveguide.
Journal ArticleDOI
Dual-mode surface-plasmon-resonance sensors using angular interrogation.
TL;DR: In this paper, an angular interrogation was used to differentiate surface binding interactions from bulk index changes at a single sensing location by using both long and short-range surface plasmons simultaneously excited at the same location and wavelength but at different angles.
Journal ArticleDOI
Optical waveguides with apodized sidewall gratings via spatial-phase-locked electron-beam lithography
TL;DR: In this article, the authors describe a technique to fabricate Bragg gratings in the sides of optical waveguides using a single lithographic step, particularly suited to the apodized gratings required for add/drop filters in dense-wavelength-division multiplexing.
Journal ArticleDOI
Controlled Magnetic Reversal in Permalloy Films Patterned into Artificial Quasicrystals
V. S. Bhat,Joseph Sklenar,Barry Farmer,Justin Woods,Jeffrey Todd Hastings,S. J. Lee,John B Ketterson,L. E. De Long +7 more
TL;DR: Micromagnetic simulations compare well to experimental dc hysteresis loops and ferromagnetic resonance spectra and indicate that systematic control of magnetic reversal and domain wall motion can be achieved via tiling design, offering a new paradigm of magnonic quasicrystals.
Journal ArticleDOI
Optimal self-referenced sensing using long - And short - range surface plasmons
Jeffrey Todd Hastings,Jing Guo,Phillip D. Keathley,P. B. Kumaresh,Yinan Wei,S. Law,Leonidas G. Bachas +6 more
TL;DR: Dual-mode surface-plasmon resonance sensors use both long- and short- range surface plasmon waves to differentiate surface binding interactions from interfering bulk effects and a range of reasonable design parameters provides nearly optimal performance.
