A Lab-on-Chip (LoC) is a miniaturized system capable of integrating each step of biological and chemical analysis (injection, reaction, separation and detection) in one single device. In some cases, the biomolecular detection is performed measuring the effect of the analyte on the light propagation in a waveguiding structure. This effect is usually quantified “off-chip” by measuring the output light power of the optical waveguide with the help of Bragg gratings, optical fibers and prisms. Within this framework, we present an integrated optoelectronic device based on an evanescent glass-diffused waveguide, optically coupled with a hydrogenated amorphous silicon (a-Si:H) photosensor for “on-chip” biomolecular detection.

Abstract
A Lab-on-Chip (LoC) is a miniaturized system capable of integrating each step of biological and chemical analysis (injection, reaction, separation and detection) in one single device. In some cases, the biomolecular detection is performed measuring the effect of the analyte on the light propagation in a waveguiding structure. This effect is usually quantified “off-chip” by measuring the output light power of the optical waveguide with the help of Bragg gratings, optical fibers and prisms. Within this framework, we present an integrated optoelectronic device based on an evanescent glass-diffused waveguide, optically coupled with a hydrogenated amorphous silicon (a-Si:H) photosensor for “on-chip” biomolecular detection.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
