Title: Innovations of Lars Johan Albinsson Nilsson
Introduction
Lars Johan Albinsson Nilsson is a notable inventor based in Suwon, South Korea. He has made significant contributions to the field of optical technology, particularly in the development of optical fiber amplifiers. With a total of 3 patents to his name, his work has had a considerable impact on telecommunications.
Latest Patents
One of his latest patents is an optical fiber amplifier that includes a first optical fiber doped with erbium and phosphorous. This amplifier is designed to enhance signal light excited by the erbium. It features a second optical fiber connected to one end of the first optical fiber, which is doped with erbium and aluminum. This second fiber has a gain spectrum slope that is opposite to that of the first fiber, allowing for effective amplification of the signal light output. Additionally, a pumping laser source is connected to the other end of the first optical fiber to excite the erbium in both fibers. A light coupler is also included to couple the pumping light to the signal light, ensuring optimal output.
Another significant patent is an erbium doped fiber amplifier (EDFA) suitable for amplifying long wavelength light signals in the range of 1570 to 1610 nm. This invention includes a pump light source that generates pump light in the 980 or 1480 nm band. It also features a light coupler for coupling the pump light to the received light signal, along with first and second optical fibers doped with erbium ions. An isolator is positioned between the two fibers to improve the gain and noise figure of the EDFA, making it highly effective for long wavelength applications.
