We present a detailed design of an optical biosensor using polymeric waveguides intended for blood glucose concentration measurements. Our proposed device is based on a vertical two-waveguide ARROW structure, simplifying fabrication and avoiding post tuning of sensor parameters. The theoretical analysis based on coupled mode theory and transfer matrix techniques is presented whereby all device dimensions and parameters are calculated. For a 2 cm sensor, output optical power in one guide can swing by approximately 17% depending on glucose concentration. Such results represent a significant improvement in performance when compared with conventional Mach-Zehnder sensors.read more

A coupled mode formulation by reciprocity and a variational principle
TL;DR: In this paper, a coupled mode formulation for parallel dielectric waveguides is presented via two methods: a reciprocity theorem and a variational principle, which is shown analytically that the conventional theory violates both power conservation and reciprocity by as much as 55 percent and the Hardy-Streifer theory by 0.033 percent.
