  • Demonstration of slot-waveguide structures on silicon nitride / silicon oxide platform
  • 2007
  • In: Optics Express. - 1094-4087. ; 15:11, s. 6846-6856
  • 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.

  • Slot-waveguide biochemical sensor
  • 2007
  • In: Optics Letters. - 0146-9592 .- 1539-4794. ; 32:21, s. 3080-3082
  • Journal article (peer-reviewed)abstract
    • We report an experimental demonstration of an integrated biochemical sensor based on a slot-waveguidemicroring resonator. The microresonator is fabricated on a Si3N4-SiO2 platform and operates at a wavelength of 1.3 mu m. The transmission spectrum of the sensor is measured with different ambient refractive indices ranging from n = 1. 33 to 1.42. A linear shift of the resonant wavelength with increasing ambient refractive index of 212 nm/refractive index units (RIU) is observed. The sensor detects a minimal refractive index variation of 2 X 10(-4) RIU.
