Building on the improvements in high-resolution lithography for silicon, one can create artificial dielectrics, periodic structures in silicon photonics with periods substantially smaller than a wavelength of light in the material. This paper discusses the theory and applications of these subwavelength structures.

This paper reviews optical modulators in silicon, which has become a very rich topic, including Mach–Zehnder modulators and ring modulators. The tradeoffs in design to achieve high speed with minimal drive voltage and insertion loss are studied.
By T. Asano and S. Noda
This paper reviews the history of 2-D photonic crystal slabs based on silicon photonics, focusing on ultrasmall cavities with ultrahigh-quality factor, and their applications as add/drop filters and Raman lasers. Ways to establish strong coupling between distant nanocavities are also discussed.
