Abstract A full polymeric optofluidic Fabry–Perot (FP) resonator with a high quality factor (Q) is proposed and tested. The device is based on multilayer optical polymeric films that act as high reflectivity interference mirrors. The all-polymeric laminated structure avoids any deposition or etching process, simplifying the fabrication procedure while retaining a high quality optical surface.

A multifunctional lab-on-a-chip platform for spectroscopic analysis of liquid samples based on optofluidic jet waveguide is reported. The optofluidic detection scheme is achieved through total internal reflection arising in a liquid jet of only 150 µm diameter, leading to highly efficient signal excitation and collection. This results in a optofluidic chip with alignment-free spectroscopic detection scheme, which avoids any background from the sample container.
