Broadband etching-free metal grating couplers embedded in titanium dioxide waveguides
Résumé
Embedded metal grating couplers into titanium dioxide layer are proposed. A coupling efficiency better than 20 % is experimentally demonstrated with a 3-dB bandwidth of 86 nm in agreement with simulation results. This allowed us to perform error-free transmissions of 10 Gbit/s wavelength multiplexed signals in the C-band.
