Title: Mitsuo Kitamura: Innovator in Optical Technology
Introduction
Mitsuo Kitamura is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of optical technology, holding a total of 9 patents. His work focuses on enhancing the efficiency and functionality of optical systems.
Latest Patents
One of his latest patents is the "Supervisory signal transmitter and method." This invention involves outputting an idle signal during intervals when a supervisory signal is not transmitted. The idle signal differs in frequency but is substantially equal in maximum power to the supervisory signal. The duty ratio of the idle signal is designed to ensure that both signals are nearly equal in average power. The transmitter features a switcher that alternates between the supervisory and idle signals, controlled by a command signal for supervisory and control purposes. The laser diode is then driven by the switcher's output to transmit both signals effectively.
Another notable patent is the "Optical amplifier and optical transmission system." This invention includes an optical amplifier equipped with redundant excitation light sources for exciting rare earth doped optical fibers, such as Erbium Doped Fiber (EDF). The design minimizes the loss of excitation light, ensuring effective introduction to the EDF. The optical amplifier maintains a predetermined total of excitation light introduced to the EDF and can switch between excitation light sources unless the output from each source is zero.
