An optical system for optical communications is composed of a transparent material having a refractive index distribution formed by changing the molar ratio of metal oxide with valence of 2 or more. The metal oxide with valence of 2 or more includes, for example, Fe O . Using such an optical system for optical communications, optical communication components such as an optical fiber collimator and an optical isolator are composed.
