Abstract
Disclosed is a silicon photonics-based optical transmission apparatus. The apparatus includes an optical modulator chip of a ground-signal-ground (GSG) electrode array including two phase shifters for differential driving, a sub-substrate including a metal electrode of a periodic pattern to connect two ground metal electrodes to each other at a GSG electrode connected to each of the two phase shifters, and a solder bump having a same periodic pattern as the metal electrode of the sub-substrate to connect the ground metal electrodes of the optical modulator chip and the metal electrode of the periodic pattern of the sub-substrate.
