Abstract
An optical fiber, including a cylindrical core of light conducting material having a first refractive index, surrounded by a cladding having a second refractive index that is lower than the first refractive index. The optical fiber includes at least one endface formed with a cone tip for controlling the characteristics of light entering or exiting the fiber. The polish angle of the cone tip can be selected according to the desired emergence/acceptance properties of the fiber.
