Title: Leonid Kotov: Innovator in Optical Fiber Technology
Introduction
Leonid Kotov is a notable inventor based in Tucson, AZ (US), recognized for his contributions to optical fiber technology. He holds a patent for a groundbreaking invention that enhances the efficiency of fiber amplification systems.
Latest Patents
Kotov's most recent patent is for a "Bare single mode fiber amplifier/laser." This invention features a gain fiber assembly designed for use in optical fiber amplification systems, such as fiber amplifiers and fiber lasers. The technology utilizes an active or 'bare' fiber with a single glass cladding, which has an outer diameter of less than 80 µm, and preferably less than 60 µm or even 40 µm. A passive double-clad input fiber is stripped of its outer cladding and tapered to match the outer diameter of the bare fiber. This design allows for a glass-fluid or glass-vacuum interface along the taper, providing guidance of the pump into and along the cladding of the bare fiber. The invention achieves a numerical aperture greater than 1 for a vacuum or gases and greater than 0.8 for liquids, enabling much shorter fiber lengths to reach maximum signal power and higher pump conversion efficiencies. Kotov holds 1 patent.
