Title: Yasuyuki Ozeki: Innovator in Optical Signal Technology

Introduction

Yasuyuki Ozeki is a prominent inventor based in Ichihara, Japan. He has made significant contributions to the field of optical signal technology, holding a total of 2 patents. His work focuses on developing devices and methods that enhance the generation and detection of optical signals.

Latest Patents

Ozeki's latest patents include a "Synchronous Optical Signal Generating Device" and a "Synchronous Optical Signal Generating Method." The synchronous optical signal generation device features an optical phase detector that compares the phase of a reference optical signal with that of an optical beat signal to generate a phase error signal. It also includes a shaping mechanism that shapes the phase error signal and a voltage-controlled optical signal generator that produces an optical beat signal based on the shaped phase error signal. This device outputs the optical beat signal while feeding it back to the phase detector.

Another notable patent is the "Lock Detector and Optical Phase-Locked Loop System." This apparatus detects the lock of an optical phase-locked loop by utilizing a first phase detector that compares the phases of an input light signal and a beat light signal. It outputs a first phase comparison signal, which is then processed by a loop filter. The system includes a phase shifter that adjusts the phase of the beat light signal, ensuring that the phase comparison signal is not zero when the two light signals synchronize.
