Latest Patents

One of his latest patents is titled "Systems and methods to increase pump conversion efficiency of an optical fiber." This invention focuses on improving the pump conversion efficiency of an L-band fiber amplifier using a multimode pump source. By directly absorbing multimode light, including 915 nm, an active fiber core region co-doped with both erbium and ytterbium can provide gain to the L-band signals through stimulated emission. Additionally, the unwanted C-band amplified spontaneous emission (ASE) light generated from this active fiber core can be absorbed by another active fiber core region doped with erbium, providing further gain to the L-band signals. The active regions and cladding can be configured to match a given spatial mode of the optical signal, and signal-pump combiners with end-coupling or side coupling can be utilized.

Another significant patent is the "Method of coupling optical fibers, and optical coupler." This patent describes a method for optically coupling a first optical fiber and a second optical fiber. The method involves bringing the free end of the first optical fiber, the second optical fiber, and a liquid into close proximity within a coupling region. The free end of the first optical fiber, having a dimension below a critical dimension, moves within the liquid to contact the second optical fiber along a specified coupling length, thereby optically coupling the two fibers.
