Pk. Spohn, UNDERSTANDING GRATING COUPLER SENSOR (GCS) DATA WITHOUT ENGAGEMENT OFTHE SYSTEM OF MODE EQUATIONS, Sensors and actuators. A, Physical, 56(3), 1996, pp. 227-232
The hydration properties of SiO2-TiO2 waveguides are investigated in s
itu using the grating coupler sensor (GCS) set-up. The strictly linear
ly dependent effective refractive indices of guided TE(0) and TM(0) li
ght modes are discussed as an implication of the resonance phenomenon
at thin dielectic film gratings.
