摘要：

A fiber-optic UV sensor based on azobenzene dye-doped polycarbonate film coated on a side-polished single mode fiber is proposed and demonstrated. The change of the refractive index of the film by exposure to UV results in a shift of the resonance wavelength in the device. The repeatable operation of the sensor is verified. The sensitivity, which is the shift of resonance wavelength per unit UV power density, is measured to be 2.35 nm/(mW/cm(2)). The response time of the sensor is shown to be 26s.
