Title: Innovations of Tatsuro Kishida
Introduction
Tatsuro Kishida is a prominent inventor based in Fukuoka, Japan. He has made significant contributions to the field of optical technology, holding a total of 2 patents. His work focuses on advancements in optical transmission methods, which are crucial for modern communication systems.
Latest Patents
Kishida's latest patents include innovative designs for optical transmitters. The first patent describes an optical transmitter that incorporates a dummy optical source, a polarized wave beam coupler, and an auto gain control (AGC)-system amplifier. This design allows the dummy optical source to output a dummy signal with a wavelength identical to that of the optical packet signal. The polarized wave beam coupler multiplexes the dummy signal with the optical signal, ensuring orthogonality and producing an effective output signal. The AGC-system amplifier then amplifies this output signal based on the power difference between the input and output of an optical amplifier.
The second patent also focuses on an optical transmitter, which includes an amplifying unit, a monitor, an identifying unit, and a controlling unit. The amplifying unit enhances an optical signal that contains a mixed optical packet signal. The monitor tracks the power of the optical signal at both the input and output stages of the amplifying unit. The identifying unit determines the optical packet signal sections based on the monitoring results, while the controlling unit adjusts the amplification factor of the amplifying unit according to the power differences identified.
