Abstract:
A second substrate is formed on a first substrate. The second substrate includes a Mach-Zehnder modulation unit and a coplanar line. Further, the second substrate is formed on and bonded to the first substrate via an adhesive layer made of a non-conductive adhesive. The Mach-Zehnder modulation unit has an optical modulation region by an electro-optic effect. The coplanar line transmits a modulated signal to the optical modulation region.
