RT Conference Proceedings T1 Low limit of detection silicon photonic sensor with extremely-low-cost laser source A1 Leuermann, Jonas A1 Fernández-Gavela, Adrián A1 Lechuga, Laura M. A1 Sánchez-Postigo, Alejandro A1 Halir, Robert A1 Molina-Fernández, Íñigo K1 Fotónica K1 Biosensores K1 Rayos láser AB Integrated photonic biosensors have demonstrated low bulk detection limits down to 1e−7 refractive index units.Nevertheless, most rely on expensive optical sources, such as DFB lasers. Here, we experimentally demonstrate that with adequatesensor design comparable detection limits are achievable with a low-cost Fabry-Perot laser.
