Journal ArticleDOI
Microring resonator channel dropping filters
TL;DR: In this article, a method of coupling of modes in time was proposed to simplify both the analysis and filter synthesis aspects of these devices, and the response of filters comprised of an arbitrarily large dumber of resonators may be written down by inspection, as a continued fraction.
Journal ArticleDOI
Photonic-bandgap microcavities in optical waveguides
James Foresi,Pierre R. Villeneuve,J. Ferrera,E.R. Thoen,Günter Steinmeyer,Shanhui Fan,John D. Joannopoulos,Lionel C. Kimerling,Henry I. Smith,Erich P. Ippen +9 more
TL;DR: In this paper, the authors measured microcavity resonances in two-and three-dimensional photonic-bandgap (PBG) structures integrated directly into a sub-micrometre-scale silicon waveguide.
Journal ArticleDOI
Ultra-compact Si-SiO 2 microring resonator optical channel dropping filters
Brent E. Little,James Foresi,Günter Steinmeyer,E.R. Thoen,Sai T. Chu,Hermann A. Haus,Erich P. Ippen,Lionel C. Kimerling,Wayne Greene +8 more
TL;DR: In this paper, a compact optical channel dropping filter incorporating side-coupled ring resonators as small as 3 /spl mu/m in radius is realized in silicon technology.
Journal ArticleDOI
Effect of size and roughness on light transmission in a Si/SiO2 waveguide: Experiments and model
Kevin K. Lee,Desmond R. Lim,Hsin-Chiao Luan,Anuradha M. Agarwal,James Foresi,Lionel C. Kimerling +5 more
TL;DR: In this article, the effect of miniaturization and surface roughness on transmission losses within a Si/SiO2 waveguide system, and explain the results using a theoretical model was evaluated.
Journal ArticleDOI
Metal contacts to gallium nitride
TL;DR: In this paper, the authors report measurements on the nature of aluminum and gold contacts to GaN and find a direct correlation between barrier height and work function of the metal, consistent with the strong ionic character of GaN.
