TY - JOUR ID - citeulike:910272 L3 - citeulike-article-id:910272 N2 - We present a highly efficient optical field concentrator that is capable of confining optical field in nanometer-thin low-index media with very high optical confinement factor. The structure is made of multiple-layered low-index nanolayers embedded in high-index silicon waveguides. By creating multiple high-index-contrast interfaces, the normal field in the low-index nanolayer regions is significantly enhanced. It subsequently results in a very high optical confinement and power density in these regions. With the help of numerical simulation tools, the guiding and propagating characteristics of the new structure are studied and presented. The optimal structures have demonstrated confinement factors and normalized power densities in the range of 30%-60% and 20-160 mum^-2 for the 5-20-nm thin low-index multiple nanolayers IS - 9 JF - Quantum Electronics, IEEE Journal of EP - 890 TI - Optical field concentration in low-index waveguides VL - 42 SP - 885 KW - anti-index-guiding KW - waveguides AU - Feng, Ning-Ning AU - Michel, J AU - Kimerling, LC PY - 2006/09/25/ UR - http://dx.doi.org/10.1109/JQE.2006.880061 ER -
