Si Photonics and Fiber to the Home

This paper describes Si photonics and the key application to fiber-to-the-home (FTTH). Mass production in terms of complementary metal-oxide-semiconductor technology is a prerequisite for Si photonics to provide a cost-effective solution, and FTTH should meet this requirement. We describe a design of the FTTH chip architecture with wavelength-division multiplexing based on ring-resonator demultiplexers and multiplexers. The grand challenge of Si photonics for this application is the production of Ge photodetectors and modulators.
