Latest Patents
One of his latest patents is titled "Efficient in-band pumping of Holmium-doped optical fiber amplifiers." This invention focuses on creating a fiber-based optical amplifier that operates at an eye-safe input signal wavelength within the 2 μm region. The design includes a section of Holmium (Ho)-doped optical gain fiber, with a pump source configured to provide light at an absorption-dominant pump wavelength, typically between 1800-1900 nm. This selection minimizes the impact of spontaneous emission from the pump on the gain achieved at higher wavelengths, thereby reducing crosstalk between the signal and pump wavelengths.
Another significant patent is "Broadband hybrid optical amplifier operation in eye-safe wavelength region." This invention proposes a hybrid optical amplifier that consists of a preamplifier element made of single-clad Ho-doped optical fiber and a power amplifier element formed of single-clad Tm-doped optical fiber. The preamplifier imparts gain to an input signal while the power amplifier provides additional gain, ensuring that only wavelength components within a defined transmission bandwidth are output.
