Title: Yasunori Michitsuji: Innovator in Optical Technology

Introduction

Yasunori Michitsuji is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of optical technology, holding a total of 2 patents. His work focuses on enhancing optical coupling and manufacturing methods for optical modules.

Latest Patents

One of his latest patents is an "Optical sub-assembly with glass member physically contact with external fiber." This invention discloses an optical receptacle that enhances the optical coupling tolerance. Instead of using a conventional coupling fiber, the optical receptacle features a glass member with a diameter that closely matches that of the external fiber. This glass member, held by a support, has a convex surface that contacts the top of the external ferrule, along with another surface inclined with the optical axis to minimize light reflection back into the optical device. The homogeneous distribution of the refractive index in the glass member helps reduce fluctuations in optical coupling with the external ferrule.

Another significant patent is the "Method for manufacturing an optical module." This invention outlines a method for creating an optical subassembly, even when there are positional deviations among components that could affect the direction of the optical output beam. The method involves determining the optimal position (x, y, z) for maximum optical coupling between the stub and the optical device. Subsequently, the direction of the optical output beam is calculated, and the inclined direction of the stub's end surface is aligned accordingly.
