Recent advances in manufactured silicon photonics

The need for low-energy high bandwidth optical solutions is driving the acceptance of silicon photonics as the platform of choice to address connectivity bottlenecks. Kotura has focused on the development of a manufacturable silicon photonics platform to demonstrate the practical realization of this technology. In this paper, we will review the progress in the development of key photonics components on the 3 μm silicon-on-insulator (SOI) platform, including mode transformers, variable optical attenuators (VOAs), wavelength division multiplexers, Ge photodetectors, and Ge modulators. We will also review recent advances in the monolithic integration of the key building blocks to form a highperformance Terabit/s wavelength division multiplexed (WDM) receiver.
