    Abstract: This invention teaches a method for fabricating a microlens within a window of a laser diode assembly, and a laser diode assembly fabricated in accordance with the method. The method includes the steps of (a) providing a laser diode assembly that includes a window that is substantially transparent at wavelengths emitted by a laser diode within the assembly, the window comprising a wavelength-selective absorber of electromagnetic radiation; and (b) irradiating a portion of a surface of the window with electromagnetic radiation having wavelengths within a range of wavelengths that are absorbed by the wavelength selective absorber such that a portion of the electromagnetic radiation is absorbed for heating and melting the material adjacent to the surface region, whereby the melted material rises up above the surface to form, when re-solidified, the microlens. In one embodiment of this invention the step of irradiating includes a step of focussing the electromagnetic radiation to have a shape that corresponds to a shape of the microlens. In another embodiment of this invention the step of irradiating includes a step of translating the window with respect to the electromagnetic radiation so as to form a generally cylindrical microlens. The microlens may be so formed to have a length and width in the range of micrometers to hundreds of micrometers.

    Abstract: Disclosed is a method of fabricating an optical fiber preform using a modified chemical vapor deposition method and a nonlinear optical fiber fabricated using the method, in which an impurity component is doped after both ends of a quartz glass tube are partially collapsed, so that an impurity doping process can be stably executed and the doped quantity of the impurity component can be increased. The method comprises the steps of: forming a cladding layer and a core layer in a quartz glass tube; partially sintering the core layer; partially shrinking both ends of the quartz glass tube, in which the cladding layer and the core layer partially sintered are formed; and doping a sintered portion of the core layer with an impurity component, so that the optical fiber preform fabricated has a predetermined function.
