WebThe dispersion of the refractive index and extinction coefficient in the wavelength range of 190−900 nm was studied. The off-resonant refractive indices of the prepared hybrid thin films T10−T90at 633 nm were in the range of 1.505−1.867 as the titania content linearly increased from 2.9 to 70.7 wt %. WebIn this regard, Tapered Optical Fibers Sensor (TOFS) is emerging due to its higher sensitivity, real-time specimen, and practical measuring capabilities. The sensitivity of a typical TOFS is 0.0001 RIU (Refractive Index Units) meaning the device is capable of detecting a 0.0001 change in refractive indices.
