Abstract
The present invention discloses a GSG track-type radio-frequency electrode, a silicon-based traveling-wave electrode light modulator, and a preparation method, and relates to the field of high-speed electro-optical chips. The GSG track-type radio-frequency electrode includes a GSG-type planar electrode, where a track electrode used for delaying an electric field is periodically added to one side or dual sides of the GSG-type planar electrode, and the track electrode is connected to a ground electrode of the GSG-type planar electrode. The silicon-based traveling-wave electrode light modulator includes the GSG track-type radio-frequency electrode and a conventional silicon-based traveling-wave electrode light modulator, and the GSG track-type radio-frequency electrode is connected to an active region of the silicon-based traveling-wave electrode light modulator by using through holes between electrode layers. The present invention can improve parameter design freedom of an electrode and realize effective signal parameter matching.
