“…18(c) shows a cross section of this EPIC technology, which leverages local siliconon-insulator (SOI) for the photonic components and selective epitaxial grown bulk silicon for the high-performance electronic components [180]. Beside applications related to high-speed optical communication [181]- [184], EPIC technologies have also successfully been applied for sensor applications [185], [186], showing its great potential. Significant progress has been made recently, pushing the Ge-photodiode bandwidth toward 110 GHz [187], which will enable the use of this technology for next-generation silicon photonic data communication.…”
