Abstract
An apparatus and method of manufacturing a wavelength converter of an optical fiber type, having a core and a clad covering the core. At least one of the core and clad is made of a nonlinear optical material such that copious amounts of second harmonic light are emitted form a light emitting end face of the optical fiber. Grooves and/or flanges are formed in or on the clad or a transparent layer covering the clad. The transparent layer also covers the light emitting end face of the optical fiber. A collimating surface is formed on the transparent layer at the light emitting end face for collimating the second harmonic light emitted. Various molds are used to form different collimating surfaces, grooves, and flanges in and on the transparent layer.
