Biosensing configurations using guided wave resonant structures Academic Article uri icon

abstract

  • Abstract. Resonant structures are characterized by a high quality factor representing the sensitivity to perturbations in a cavity. In guided wave resonant structures the optical field is evanescent, forming a region where the resonance can be modified by externally varying the refractive index within this evanescence region. The resonance nature of these structures then allows high sensitivity to analytes, gases, or other external index perturbations down to the order of 10-8 RIU. In this article several configurations of …
