Claim:
1. A semiconductor structure comprising: a semiconductor-on-insulator (SOI) substrate including, from bottom to top, a (111) silicon layer, a buried insulator layer and a (100) silicon layer; a field effect transistor (FET) located on a portion of the (100) silicon layer; a light-emitting element separated from the FET and embedded in the SOI substrate, wherein the light-emitting element is laterally surrounded by the (100) silicon layer, the buried insulator layer and an upper portion of the (111) silicon layer; and a patterned portion of the (111) silicon layer located beneath the light-emitting element, the patterned portion of the (111) silicon layer comprising trenches exposing portions of a bottommost surface of the light-emitting element.
