Title: Masao Shibata: Innovator in Laser Technology

Introduction

Masao Shibata is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of laser technology, holding a total of 11 patents. His work focuses on enhancing the performance and functionality of wavelength tunable laser apparatuses.

Latest Patents

One of Masao Shibata's latest patents is a method to tune the emission wavelength of a wavelength tunable laser apparatus. This innovative laser apparatus integrates a wavelength tunable laser diode (t-LD) with a semiconductor optical amplifier (SOA) and includes a wavelength monitor featuring an etalon filter. The current emission wavelength is determined by the ratio of the magnitude of a filtered beam passing through the etalon filter to a raw beam that does not pass through it. The method begins by setting the SOA in an absorbing mode to detect stray components that may disturb the wavelength monitor. It then corrects the ratio of the beams by subtracting the contribution from the stray component.
