• Enhanced Goos-Hanchen shift
• Cascaded waveguide structure

An narrow band optical filter based on an enhanced Goos-Hanchen shift utilizing cascaded waveguide structure is proposed. We demonstrate in an experiment that a filter with 3 dB bandwidth of 0.19 nm and extinction ratio of 6.7 dB around a light wavelength of 859 nm is realized.
