Photonic crystal power dividers using L-shaped bend based on ring resonators
收藏 引用
JOURNAL OF THE OPTICAL SOCIETY OF AMERICA B-OPTICAL PHYSICS 2008年 第8期25卷 1231-1235页
作者: Djavid, Mehrdad Ghaffari, Afshin Monifi, Faraz Abrishamian, Mohammad Sadegh KN Toosi Univ Technol Dept Elect Engn Tehran *** Iran
We propose a new type of two-dimensional photonic crystal power dividers based on ring resonators and directional couplers that can be applicable to photonic integrated circuits. The proposed power divider's mecha... 详细信息

2-D MODE TAPERING VIA TAPERED CHANNEL wave-GUIDE SEGMENTATION
收藏 引用
ELECTRONICS LETTERS 1992年 第16期28卷 1514-1516页
作者: WEISSMAN, Z HARDY, A Tel Aviv Univ. Ramat Aviv Israel
A simple and versatile 2-D mode-tapering method for a channel waveguide, which is based on tapered waveguide segmentation, is proposed. The taper can be incorporated into the waveguide at the stage of lateral channel ... 详细信息

SURFACE EMITTING 2ND HARMONIC-GENERATION IN VERTICAL RESONATOR
收藏 引用
ELECTRONICS LETTERS 1991年 第20期27卷 1882-1884页
作者: LODENKAMPER, R FEJER, MM HARRIS, JS STANFORD UNIV EDWARD L GINZTON LABSTANFORDCA 94305
The efficiency of surface emitting second harmonic generators can be significantly increased by resonating the second harmonic field in a vertical cavity structure. These resonant devices can be several orders of magn... 详细信息

FORM OF FIELD IN SMALL-OFFSET LONGITUDINAL SLOT IN BROAD WALL OF RECTANGULAR wave-GUIDE
收藏 引用
ELECTRONICS LETTERS 1992年 第1期28卷 16-17页
作者: MCNAMARA, DA JACOBS, JP JOUBERT, J Dept. of Electron. & Comput. Eng. Pretoria Univ. South Africa
A surface-patch moment method approach is used to examine the electric field distribution in longitudinal slots that have small offsets from the host rectangular waveguide centreline. It is shown that the phase of the... 详细信息

Intrinsic Fano Interference of Localized Plasmons in Pd Nanoparticles
收藏 引用
NANO LETTERS 2009年 第2期9卷 882-886页
作者: Pakizeh, Tavakol Langhammer, Christoph Zoric, Igor Apell, Peter Kall, Mikael Chalmers Dept Appl Phys S-41296 Gothenburg Sweden
Palladium (Pd) nanoparticles exhibit broad optical resonances that have been assigned to so-called localized surface plasmons (LSPs). The resonance's energy varies with particle shape in a similar fashion as is we... 详细信息
