Latest Patents

One of Savin's latest patents is titled "Inhomogeneous Broadening to Modify the Gain of an Optical Amplifier." This invention describes an optical amplifier with a gain profile that remains substantially flat and independent across a wide range of factors, including pump power and input signal characteristics. The breakthrough involves utilizing an optical resonator with a gain medium that exhibits inhomogeneous gain broadening. Notably, the amplifier employs a ring resonator, often incorporating erbium-doped fiber, and the potential addition of codopants to amplify the inhomogeneous broadening effect. A method for gain flattening within this framework introduces a pump signal at a specific wavelength, effectively clamping the gain of the medium.

Another significant patent from Savin is the "Tunable, Mechanically Induced Long-Period Fiber Grating with Enhanced Polarizing Characteristics." This development presents a novel fiber filter designed for optical communication systems, particularly useful in flattening the gain of erbium-doped fiber amplifiers (EDFAs). Such gain flattening is paramount for long-haul and dense wavelength division multiplexing (WDM) communication systems. The innovative filter comprises a periodic mechanical structure applied against a single-mode fiber, inducing wavelength-dependent loss in signals via coupling to fiber cladding modes. The ease of fabrication, utilizing standard machining equipment, adds to the practicality of this invention.
