Abstract
An optical element according to the present invention has a thin film, in which single-wall carbon nanotubes are laminated, and utilizes a saturable absorption function of the single-wall carbon nanotubes. Further, in a method for producing the optical element according to the present invention, the thin film is formed by spraying, to a body to be coated, a dispersion liquid prepared by dispersing the single-wall carbon nanotubes in a dispersion medium. Accordingly, a nonlinear optical element, which can operate in an optical communication wavelength region and which is extremely inexpensive and efficient, and a method for producing the optical element can be provided.
