Towards Extremely Sensitive Ultraviolet-Light Sensors Employing Photochromic Optical Microfiber
Dependence of responsivity (i.e., negative) on the disc radius and optical-microfiber diameter. The refractive index of the core and cladding is 1.50 and 1.38 at a wavelength of 660 nm. The UV intensity is 15 mW/cm2.
