Title: Kaoru Kinjo: Innovator in Optical Technologies
Introduction
Kaoru Kinjo is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical technologies, holding a total of 3 patents. His work focuses on advancements in optical transmission and modulation techniques.
Latest Patents
One of his latest patents is an optical transmitter that utilizes a differential encoder to generate a differentially encoded signal based on a data signal. This invention includes an RZ (return to zero) encoder that produces an electric RZ differential signal as an RZ signal in an electric area, derived from the differentially encoded signal. Additionally, a Mach-Zehnder interferometer type intensity modulator generates an optical RZ-DSPK (differential phase shift keying) signal as an RZ signal in an optical area based on the electric RZ differential signal.
Another notable patent involves a method and device for performing bi-directional transmission using a single wire. In this invention, two signal lights with different wavelengths are bidirectionally transmitted on an optical-fiber transmission line. A Raman pump light source generates a first Raman pump light with predetermined wavelengths to amplify the first signal light, while another Raman pump light source generates a second Raman pump light for the second signal light. These light sources are injected into the optical-fiber transmission line through optical combining and branching filters.
