摘要： Methods of forming a total-internal-reflection (TIR) optical fiber lens are disclosed. The methods include heating an end of an optical fiber with a defocused infrared laser beam to form a bulbous tip having a curved outer surface that defines a lens surface. The bulbous tip is laser cleaved to define a TIR facet. Light traveling in the fiber diverges at an effective fiber end and is reflected by the TIR facet through the lens surface to form an image at an image plane.

摘要： The present invention concerns a method for constructing a light coupling system wherein a grating is manufactured on the surface of a multimode waveguide and defines the entrance of the waveguide for an incident light beam, said grating comprising a repetition of patterns. The grating is defined by a set of parameters comprising: •grating period (P), separating two adjacent patterns, •grating depth (d) between the highest and the lowest point of the pattern, •incident angle mean value (θ) of the incident light with respect to the waveguide. The method comprises a step of optimization of the set of parameters to obtain an optimized second set of parameters, in order to obtain a transmission efficiency (Ce) of the incident light into said waveguide for the first or the second diffractive order exceeding 35% for unpolarized light, or exceeding 50% for polarized light, at a given wavelength of the incident light.
