“…Other important characteristics of silicon are its high thermal conductivity (149 Wm -1 K -1 ) and mechanical hardness (a Young's modulus of 150 GPa, and a Poisson's ratio of 0.17), which makes the cooling and handling of photonic devices easy. Nonlinearities in silicon are not as large as in other semiconductor materials such as III-V semiconductors, polymers, organic materials, chalcogenide compounds, etc [3]. However the CMOS compatibility of silicon photonics is a strong motivation to develop nonlinear devices within this technological platform, in addition to the already developed heavily integrated linear optical silicon photonics circuitries.…”

Silicon photonics is a technology based on fabricating integrated optical circuits by using the same paradigms as the dominant electronics industry. After twenty years of fervid development, silicon photonics is entering the market with low cost, high performance and mass-manufacturable optical devices. Until now, most silicon photonic devices have been based on linear optical effects, despite the many phenomenologies associated with nonlinear optics in both bulk materials and integrated waveguides. Silicon and silicon-based materials have strong optical nonlinearities which are enhanced in integrated devices by the small cross-section of the high-index contrast silicon waveguides or photonic crystals. Here the photons are made to strongly interact with the medium where they propagate. This is the central argument of nonlinear silicon photonics. It is the aim of this review to describe the state-of-the-art in the field. Starting from the basic nonlinearities in a silicon waveguide or in optical resonator geometries, many phenomena and applications are described—including frequency generation, frequency conversion, frequency-comb generation, supercontinuum generation, soliton formation, temporal imaging and time lensing, Raman lasing, and comb spectroscopy. Emerging quantum photonics applications, such as entangled photon sources, heralded single-photon sources and integrated quantum photonic circuits are also addressed at the end of this review.

“…In this last term, the phase mismatch parameter b has been introduced. The strength of the FWM terms depends on the coefficients g ( ) ijkl3 , which are related to the confinement of the optical modes. Therefore, FWM is stronger in waveguides where the electromagnetic field is more confined.…”

In this chapter, a new paradigm is developed for optical computation using photonic crystals. As photonic crystals are the most sophisticated optical materials to date, information processing using this structure is one of the most sought-after technologies in photonics. While the semiconductor industry is striving hard to increase the microprocessors' processing power, it is certain that the trend would not last forever as against Moore's prediction. At this juncture, photonics technologies have to compete with the upcoming quantum computing technology to emerge as a promising successor for semiconductor microprocessors. This chapter is devoted to the introduction of photonic crystals as the workhorse for an all-optical computational system with a myriad of logic gates, memory units, and networks which can be constructed using these structures.
