摘要：A PIN electro-optical traveling wave modulator () including diffraction gratings() positioned at opposing sides of an optical waveguide () that act to change the

propagation pattern of the waveguide (). The modulator () includes an N-type layer (), aP-type layer () and an intrinsic layer () acting as the waveguide (). A metal electrode () is inelectrical contact with the N-type layer (), and a metal electrode () is in electrical contactwith the P-type layer (). The electrodes () define an RF transmission line. An optical wave ()propagates along the waveguide () and interacts with the gratings () which slow theoptical wave () to match its speed to the speed of the RF wave in the transmission line. Inone embodiment, the gratings () are 2-D gratings formed by vertical holes () in thewaveguide ().
