Journal article (peer-reviewed)abstract
- We report on the first demonstration of guiding light in vertical slot-waveguides on silicon nitride/silicon oxide material system. Integrated ring resonators and Fabry-Perot cavities have been fabricated and characterized in order to determine optical features of the slot-waveguides. Group index behavior evidences guiding and confinement in the low-index slot region at O-band (1260-1370nm) telecommunication wavelengths. Propagation losses of < 20 dB/cm have been measured for the transverse-electric mode of the slot-waveguides.

Conference paper (peer-reviewed)abstract
- We demonstrate slot-waveguide microring resonators and Fabry-Perot microcavities on Si3N4/SiO2. Characterization indicates guiding and confinement in the waveguide nanometric-size low-index slot region at O-band (1260-1370nm) wavelengths. We measured propagation losses <20 dB/cm.

High efficiency silicon nitride surface grating couplers
- 2008
-
In: Optics Express. - 1094-4087. ; 16:1, s. 328-333
-
Journal article (peer-reviewed)abstract
- High efficiency surface grating couplers for silicon nitride waveguides have been designed, fabricated, and characterized. Coupling efficiencies exceeding 60 % are reported at a wavelength of 1.31 mu m, as well as angular and wavelength -3 dB tolerances of 4 and 50 nm, respectively. When the wavelength is increased from 1310 nm to 1450 nm the coupling efficiency progressively decreases but remains above 20 % at 1450 nm. The influence of the duty ratio of the grating has also been investigated: maximum coupling efficiency was obtained at 50 % duty ratio.
