Integrated Optical Refractometer based on U-shape bend Waveguide Structure for (bio-) Chemical Sensing Applications
نویسندگان
چکیده
This paper proposes and describes a design of an integrated refractive index sensor for (bio-) chemical sensing applications based on a U-shape bend waveguide structure. The proposed structure is formed by connecting four-bend waveguides and optimized using beam propagation method so that the output power has a function of refractive index of measurand liquid. The results show that the designed structure is suitable for any measurand refractive index within the range of 1.47 < n < 1.49 with a potential high resolution of n = 6x10 at n = 1.485. This suggests that the proposed structure is suitable for (bio-) chemical application. Index Term– refractometer, U-shape bend waveguide, integrated optics.
