摘要：
There is provided a cutting element for use in a hair cutting device. The cutting element includes an optical waveguide having an optical axis and a sidewall, wherein a portion of the sidewall forms a cutting face for contacting hair； wherein the optical waveguide includes a plurality of structures formed along the optical axis, the structures having a refractive index which is different to a refractive index of the optical waveguide. A hair cutting device comprising a cutting element, and a method of manufacturing an optical waveguide cutting element are also disclosed.
