Integration of polymer microfluidics with silicon photonic biosensors by one-step combined photopatterning and molding of OSTE

• We demonstrate a method for the fast and simple packaging of silicon sensors into a microfluidic package consisting of the recently introduced {OSTE} polymer. The microfluidic layer is first microstructured and thereafter dry-bonded to a silicon photonic sensor, in a process compatible with wafer-level production, and with the entire packaging process lasting only 10 minutes. The fluidic layer combines molded microchannels and fluidic (Luer) connectors with photopatterned through-holes (vias) for optical fiber probing and fluid connections. All the features are fabricated in a single photocuring step. We report measurements with an integrated silicon photonic {Mach-Zehnder} interferometer refractive index sensor packaged by these means.
