Method of making a symmetrical optical waveguide |
摘要 |
A structure for use in forming an optical component and a method of making such a component is described. The structure comprises a non-waveguiding body of optical material having a concentration of a photorefractive-sensitive component in the body such that upon irradiation of a part of the body by a beam of actinic radiation, the refractive index of the irradiated part is increased. The method of making the optical component comprises providing a non-waveguiding body of optical material; providing a concentration of a photorefractive-sensitive component in the body; contacting the non-waveguiding body of optical material with an atmosphere comprising one of hydrogen, deuterium and mixtures thereof; and exposing a part of the non-waveguiding body of optical material to actinic radiation such that the refractive index of the exposed part is increased. Such a structure and method can be used to form symmetrical planar waveguides, optical fiber waveguides and other optical components such as gratings.
