摘要： PROBLEM TO BE SOLVED: To provide a moisture-resistant electro-optical device used in optical fibre telecommunication. SOLUTION: A structure of an electro-optical modulator embedded in a device has an additional set of biasing electrodes for applying a bias voltage to set up the operating point. Since it can operate the RF electrode used to modulate input optical signals at a DC zero bias, the electrode corrosion by galvanic effects and other effects can be suppressed inside non-airtight packages. The biasing electrodes are at least partly separated from the substrate by the buffer layer having some conductivity in an embodiment. This conductive buffer layer reduces the optical loss by the biasing electrodes, and also makes the DC drift small. COPYRIGHT: (C)2008,JPO&INPIT
