Step index optical fibre physics
網頁The type of optical fibre you need to know about are step-index optical fibres. These consist of two main parts: 1. A core made of a high-refractive index material 2. Cladding … 網頁The step-index fiber was tested at a wavelength of 1.55 µm, while the graded-index fiber was tested at a wavelength of 1 µm. The step-index fiber was created using two …

http://www.alevelphysics.org.uk/optics.html 網頁An optical fiber consists of three concentric elements, the core, the cladding and the outer coating, often called the buffer. The core is usually made of glass or plastic. The core is the light-carrying portion of the fiber. The cladding surrounds the core. The cladding is made of a material with a slightly lower index of refraction than the core.
