Waveguide coupler formed by a graded photonic crystal

The coupling between a conventional dielectric waveguide and a photonic crystal waveguide is studied. The coupling methods studied in this work include graded photonic crystal coupler, photonic crystal taper, waveguide taper and parabolic mirror coupler. The measurement and simulation results show t...

Beschreibung
Zusammenfassung:	The coupling between a conventional dielectric waveguide and a photonic crystal waveguide is studied. The coupling methods studied in this work include graded photonic crystal coupler, photonic crystal taper, waveguide taper and parabolic mirror coupler. The measurement and simulation results show that the graded photonic crystal coupler has a higher coupling efficiency in a short coupling length.
