The majority of silicon photonic communications have so far been limited to telecom [31] and datacom applications, [32] [33] where the reach is of several kilometers or several meters respectively. Silicon photonics, however, is expected to play a significant role in computercom as well, where optical links have a reach in the centimeter to ...
The slot-waveguide was born in 2003 as an unexpected outcome of theoretical studies on metal-oxide-semiconductor (MOS) electro-optic modulation in high-confinement silicon photonic waveguides by Vilson Rosa de Almeida and Carlos Angulo Barrios, then a Ph.D. student and a postdoctoral associate, respectively, at Cornell University.
The operation of the hybrid plasmonic waveguides can be explained using the concept of mode coupling. The most commonly used hybrid plasmonic waveguide consists of a silicon nanowire placed very near a metal surface and separated by a low index region. The silicon waveguide supports dielectric waveguide mode, which is mostly confined in silicon.
The light travelling through the waveguides in an optical ring resonator remains within the waveguides due to the ray optics phenomenon known as total internal reflection (TIR). TIR is an optical phenomenon that occurs when a ray of light strikes the boundary of a medium and fails to refract through the boundary.
Nanophotonics or nano-optics is the study of the behavior of light on the nanometer scale, and of the interaction of nanometer-scale objects with light. It is a branch of optics , optical engineering , electrical engineering , and nanotechnology .
NanoCleave is a technology developed by Silicon Genesis Corporation that separates the silicon via stress at the interface of silicon and silicon-germanium alloy. [18] ELTRAN is a technology developed by Canon which is based on porous silicon and water cut. [19] Seed methods [20] - wherein the topmost Si layer is grown directly on the insulator ...
An illustration of OPC (Optical Proximity Correction). The blue Γ-like shape is what chip designers would like printed on a wafer, in green is the pattern on a mask after applying optical proximity correction, and the red contour is how the shape actually prints on the wafer (quite close to the desired blue target).
Refraction at interface. Many materials have a well-characterized refractive index, but these indices often depend strongly upon the frequency of light, causing optical dispersion.
