| titleOfInvention | Silicon-based integrated laser chip flip-chip coupling structure |
| abstract | The invention discloses a flip-chip coupling structure of a silicon-based integrated laser chip, wherein an active laser chip is arranged on the left side of the structure, a passive silicon-based chip is arranged on the right side of the structure, a groove is formed in the left side of the passive silicon-based chip, and the active laser chip is bonded with the passive silicon-based chip by being inversely arranged in the groove; the passive silicon-based chip is internally provided with silicon-on-insulator, and an epitaxial part of the silicon-on-insulator is used as a coupling and receiving channel of light; the top layer and the bottom layer of the active laser chip are provided with metal contacts connected with the electrodes; the active laser chip is used as an excitation source to emit light, and the light enters an epitaxial channel of the silicon-on-insulator through evanescent field coupling to form optical field transmission. The invention can realize the high-efficiency optical coupling of the active device and the passive device and lays a foundation for the large-scale photon integration technology. |
