Optical Grating Waveguide Sensors Based оn Chalcogenide Glasses

详细

The operating principle of the optical grating waveguide sensors is considered. The waveguide sensitivity and detection limit of sensors with waveguides of oxide and chalcogenide glasses are compared. The advantages of the grating waveguide sensors with waveguides with a high contrast of refraction indices are shown. The conditions of obtaining a maximum waveguide sensitivity of the grating waveguide sensors are formulated.
