Microcavity filters in ultra-small Silicon on Insulator (SOI) waveguides are investigated. The microcavities are formed by one-dimensional photonic crystals (PhC) in Fabry-Perot structures, which are embedded in planar strip waveguides with 500nm width and 220nm height.
The photonic crystal microcavities are fabricated in a CMOS environment using 248nm DUV lithography. Several types of PhC micorcavities were optically characterized by a measurement setup using an external cavity laser (ECL) (tunable from 1520nm to 1630nm) and a nano-positioning system with an active differential intensity alignment system for the coupling of light.
Results of a number of different cavity filters, for instances multi-cavity, first and higher order cavities will be presented. Furthermore the measured transmission characteristics will be compared with simulations.
