Title: Michiharu Itou: Innovator in Planar Lightwave Circuit Technology

Introduction

Michiharu Itou is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of planar lightwave circuits, holding a total of 2 patents. His work has been instrumental in advancing technologies that utilize lightwave circuits for various applications.

Latest Patents

One of Itou's latest patents is focused on a manufacturing method for a planar lightwave circuit device. This innovative method involves forming a lift-off mask layer on a planar lightwave circuit composed of cores and a cladding. The lift-off mask layer is then exposed to light using a mask that contains multiple first patterns corresponding to the cores and second patterns formed on at least one side of each first pattern. Following this, a wiring pattern material layer is deposited on the exposed lift-off mask layer. The lift-off mask layer is subsequently stripped off, resulting in the formation of real patterns corresponding to the first patterns and dummy patterns corresponding to the second patterns from the wiring pattern material layer.
