| We report a method that enables the combination of integrated optical systems with on-chip fluid handling for chemical analysis, without compromising the functionality of either part. Utilizing a selective isotropic plasma etch of a sacrificial chromium etch-stop layer, fluidic connections can be made down to buried nanostructured optical sensing elements in a controlled manner. We describe the fabrication method and present an example application to a label-free assay of protein concentration based on optical slot-waveguide micro-ring resonator refractive index sensors. | |
