Patent ReferencesBroadband, low drive voltage, electrooptic, intergrated optical modulator Traveling-wave reflective electro-optic modulator Patent #: 5886807 InventorsApplicationNo. 966197 filed on 11/07/1997US Classes:356/477, Using fiber or waveguide interferometer385/2, Electro-optic385/3Phase modulation typeExaminersPrimary: Kim, Robert H.Assistant: Lee, Andrew H. Attorney, Agent or FirmInternational ClassG01B 009/02AbstractA Mach-Zehnder interferometer has electrodes configured to act as a microe transmission line. The optical waveguide arms have a reflective coating on their distal ends so that light is reflected back through the arms. The microwave transmission line is open-ended in a vicinity of the reflective coating so that microwave energy is reflected at the open end. Thus, the interferometer supports a traveling wave in a reflective configuration, and the distance over which interaction takes place can be effectively doubled. | |
