Latest Patents

One of Sergej's key patents is titled "Method for coupling of semiconductor lasers into optical fibers." This patent presents a method for efficiently coupling beams from semiconductor lasers into optical fibers. The technique involves modifying the end surface of the optical fibers to improve coupling efficiency. It combines the shaping of the fiber end face with an axial variation of the refractive index of the fiber end face material, depending on the distance from the fiber end face surface. A preferred embodiment of this method utilizes an axial gradient-index lens (AGRIN lens) fabricated directly on the fiber end face, which significantly enhances the coupling of a laser beam into the fiber. This method can also be applied in other scenarios where optical fibers with spherical or more complex end face surfaces need to be manufactured.
