Silicon photonic integrated circuits

Abstract

The chapter covers fundamentals of Silicon Photonic ICs including the driving forces, basic physics, technological implementations, current state of the art, ongoing R&D and trends for future research. The treatment includes all relevant devices excluding Silicon Photonics based sources. The chapter comprises specific sections on wavelength selective devices such as delay-line based- and ring resonator-based spectral filters, and covers grating couplers, waveguide-integrated germanium photodetectors, and optical isolators as well. Nonlinear optic devices constitute a more advanced topic, and its coverage includes fundamental aspects and a number of corresponding devices including wavelength converters, all optical amplifiers, phase sensitive amplifiers, and a section on the design of complex Silicon Photonic ICs.
