@conference{10902/32220, year = {2023}, month = {5}, url = {https://hdl.handle.net/10902/32220}, 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.}, organization = {This work was supported by the MCIN/AEI/10.13039/501100011033 and FEDER funds of European Comission (PID2019-107270RB-C21), and by the MCIN/ AEI /10.13039/501100011033 and NextGenerationEU/PRTR (TED2021-130378B-C21).
