    • Add-drop filter based on TiO2 coated shifted Bragg grating 

      Paul Somnath; Vartiainen Ismo; Roussey Matthieu; Saastamoinen Toni; Tervo Jani; Honkanen Seppo; Kuittinen Markku (The Optical Society, 2016)
      We present a titanium dioxide coated shifted Bragg grating in a silicon-on-insulator platform enabling optical add-drop functionality. The device works on the basis of mode conversion due to shifted sidewall structure ...

    • Bio-molecular sensors based on guided mode resonance filters 

      Saleem Rizwan Muhammad; Ali Rizwan; Honkanen Seppo; Turunen Jari (IOP Publishing, 2016)
      In this work a low surface roughness and homogenous, high refractive index, and amorphous TiO2 layer on corrugated structures of diffractive optical element is coated by Atomic Layer Deposition (ALD) for biosensors. The ...

    • Influence of an Al2O3 surface coating on the response of polymeric waveguide sensors 

      Ahmadi Leila; Hiltunen Marianne; Hiltunen Jussi; Aikio Sanna; Saarinen Jyrki; Honkanen Seppo; Roussey Matthieu (The Optical Society, 2017)
      The responses of a polymer ridge waveguide Young interferometer with and without a bilayer of Al2O3/TiO2, fabricated by atomic layer deposition, are studied and compared when applied as an aqueous chemical sensor. The phase ...

    • Modal properties of a strip-loaded horizontal slot waveguide 

      Pélisset Ségolène; Laukkanen Janne; Kuittinen Markku; Honkanen Seppo; Roussey Matthieu (Springer Nature, 2017)
      Background Channel waveguides have been developed for years to comply with the need for smaller footprint and better integration in photonics circuits. However, they are still suffering from fabrication complexity and ...
