Abstract
An optical phase modulator includes a block constituting a magnetic free layer and having a first face, a second face opposite to the first face, an entrance face different from the first face or the second face and through which light enters, and an exit face different from the first face or the second face and through which light exits. The optical phase modulator includes a first electrode disposed to the first face, either directly or not directly on the first face.
