A novel Integrated Optic (IO) grating array based gas sensor has been proposed. The array elements are coated with different polymers that interact with identified gas molecules selectively. The sensor can detect the gas molecules selectively and simultaneously.
In this paper we have proposed and analyzed a novel integrated optic racetrack resonator based biosensor. The device is capable of distinguishing compressive and tensile stresses on a cantilever due to conformational changes of protein. We have considered Bovine Serum Albumin (BSA) and Immunoglobulin G (IgG). The change of surface stress upon adsorption of IgG is compressive and of BSA is tensile...
We have deigned and simulated a compact Rib waveguide based biosensor which could produce a sensitivity of 1.8 × 10-3. Silicon On Insulator wafer is chosen with 1 μm Si which forms the core and 1 μm SiO2 cladding below that as a buffer which minimizes the substrate losses. The waveguide has been designed to support only the fundamental TE and TM modes. The optimum value of rib width W is found to...
