Optical Circuit Device, Integrated Optical Device And Method For Manufacturing Of Integrated Optical Device

Abstract

An integrated optical device includes: an optical amplifier that amplifies signal light input from the optical function element to the optical circuit element through a connection portion; and a connection tap port that is installed between the optical amplifier and the connection portion, branches a part of the signal light input from the optical function element through the connection portion, and outputs the signal light to the outside, and the connection tap port includes an input port that receives the signal light input from the optical function element to the optical circuit element through the connection portion, a demultiplexer that branches a part of the signal light, a first output port that outputs the branched part of the signal light to the outside, and a second output port that outputs a part of the branched signal light to the optical amplifier.
