Abstract
An integral optical device is disclosed that is composed of a photosensitive glass having an optical pattern developed therein by a refractive index change due to formation of colloidal metal particles and/or crystalline microphases nucleated by such particles. In a specific embodiment the pattern is composed of at least one transparent lens system having a radial gradient refractive index distribution of prescribed nature.
