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.

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.
