Paper Abstract

The design of optimized V-groove waveguides for evanescent surface sensing as well as for the exploitation of nonlinear optical effects in low index materials is presented. Morever, the leakage behaviour of horizontal ribtype slot waveguides is discussed, which has been calculated employing MaxWave, a novel simulation package of electromagnetic mode solvers for the computation of the optical field in integrated optical waveguide devices. An integrated all-polymer Mach-Zehnder interferometer based biosensing concept is presented. We show that efficient coupling of light into thin low index contrast single mode waveguides via surface gratings becomes feasible by applying a high index coating on the grating. We provide an experimental verification of this effect as well as homogeneous sensing results.
