Abstract (EN): In this paper an optofluidic chip for simultaneous determination of refractive index and acquisition of absorption or fluorescent spectra is described. The system comprises a microfluidic channel with multiple inlet/outlet for sample handling and a dual fiber optic probe, standing face to face across the channel, for the optical measurements. An FBG based Fabry Perot cavity, and a Braggmeter, allow for interferometric measurement of the refractive index while external illumination and a multimode fiber enable acquisition of the absorption/fluorescence spectra with a CCD spectrometer. Preliminary results showing the viability of simultaneous measurement are obtained from the characterization of mixed samples with distinct refractive index and dye concentrations.
