Abstract

We propose a design for high quality factor two-dimensional (2D) photonic crystal cavities on silicon-on- insulator (SOI). A quality factor of up to $1.2\times {10}^7$ with a modal volume of $2.35(\lambda /n{)}^3$ is simulated. A very high quality factor of 200,000 is experimentally demonstrated for a 2D cavity fabricated on SOI.
