Abstract :
Sensitivity of rib waveguides designed for evanescent-wave integrated optical sensors is investigated by an improved analytic approach based on Effective Index Method. Proposed procedure is applied to rib guiding structures in different CMOS-compatible technologies and rigorous results obtained by Finite Element Method are used for comparison. Agreement is demonstrated to be good even for high index contrast waveguides.
