Abstract

A method of fabricating a distributed feedback optical fiber laser, comprises the step of exposing an optical fiber (20) to a transverse light beam (30) to form a grating structure in a section of the optical fiber, the writing light beam being polarized in a direction not parallel to the axis of the section (10) of optical fiber (20).
