Abstract
In this work, we designed a fused silica lab-on-chip that combines optical techniques such as absorption, Raman scattering and fluorescence to quantify phytoplankton type and concentration in water. In the absorption stage of the chip, a Fabry-Perot resonator significantly enhances the spectral response. Scattering and fluorescence spectroscopy are considered with light focusing on sample channel. The design process, and more specifically the integrated in-chip aspheric lenses, is carried out by ray-tracing simulations.
