Abstract
A device includes a waveguide, an electrode that has a coplanar structure, and an interaction unit that is constituted such that the interaction unit is inserted into a slot of the waveguide, that is formed using an electro-optical polymer, and that acts on light passing through the waveguide according to a voltage received from the electrode. The device includes an excessive length unit that extends to an input side and an output side of the interaction unit and that is formed using the electro-optical polymer, and an other waveguide that is not connected to the waveguide and that is formed by inserting the excessive length unit into the slot located between a first doped layer that is connected to a ground electrode disposed parallel to the excessive length unit and a second doped layer that is connected to a signal electrode disposed parallel to the excessive length unit.
