Abstract
A narrow band (3dB bandwidth <2nm) transmission notch filter based on polarisation conversion within a photonic crystal waveguide is demonstrated. Signal contrast between quasi- TE and TM eigenstates reaching 40dB is achieved. Further, multiple resonant wavelength coupling between the two eigenstates is also observed. These offer a novel alternative approach to sensing and biodiagnostics compared to previous use of the band edge of a photonic crystal waveguide.
