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...
This presentation reviews the basic principles of femtosecond laser waveguide writing, as well as its application to the fields of optical communications and biophotonics. Optical waveguides mode-matched to standard single-mode fibers can be used for a variety of telecom devices such as splitters, couplers and interferometers, as well as for active devices, such as erbium-doped waveguide amplifiers...
