- Experimental characterization of a silicon photonic biosensor consisting of two cascaded ring resonators based on the Vernier-effect and introduction of a curve fitting method for an improved detection limitTom Claes
Photonics Research Group, Department of Information Technology Ghent University imec, Sint Pietersnieuwstraat 41, 9000 Gent, Belgium
Opt Express 18:22747-61. 2010..We derived formulas describing the sensor's operation, and introduced a fitting procedure that allows to accurately detect changes in the sensor response. We determined the detection limit of this first prototype to be 8.310(-6)RIU...
- Vernier-cascade label-free biosensor with integrated arrayed waveguide grating for wavelength interrogation with low-cost broadband sourceTom Claes
Department of Information Technology, Ghent University IMEC, Ghent, Belgium
Opt Lett 36:3320-2. 2011..The relaxation on the complexity of the source, moreover, offers the prospect to integrate the source and detectors to further reduce the device cost and to increase its portability...
