Optical filter based on two-dimensional photonic crystal surface-mode cavity in amorphous silicon-on-silica structure
An optical filter based on side coupling between silicon wire waveguide and two-dimensional photonic crystal surface-mode cavity is presented. The design is optimized numerically by parallel three-dimensional finite-different time-domain simulations. The device is then fabricated on amorphous silicon-on-silica structure.
The drop wavelength is observed around 1580nm. The extinction ratio of the filter is larger than 10dB and the intrinsic quality factor of the surface-mode cavity is approximately 2000.
