Silicon Photonics for Tech Innovators

This document discusses silicon photonics, which uses silicon to transmit optical information between electronic devices. It aims to provide lower cost optical components integrated into a single silicon chip. The key components discussed are silicon lasers, modulators, waveguides, and detectors. Intel's goal of "siliconizing photonics" is to build these inexpensive silicon blocks to develop integrated optical chips that can solve communication problems at higher speeds than traditional copper wiring. The document outlines Intel's breakthrough in creating a fully integrated 50Gbps silicon photonic link.

ABSTRACT

Silicon photonics is an emerging technology using standard silicon to send and receive
optical information among computers and other electronics devices .Silicon based technology
could deliver higher speed computing at lower cost.
Copper and optical fiber is also used as core interconnects technology, inside the computers.
Frequency is the speed determining factor in data transfer. As frequency increases more
losses occur in Cu, and in the case of fiber optics, it is very expensive, because which is
fabricated using exotic materials and its complexity limits application in the technology.
Silicon has the property that, while it is opaque to human eye, it is transparent in the IR
optical wavelengths. This property and limitations of Cu and optical fiber in optical connects
prompted Intel to research the construction of fiber optic components from silicon.
The goal of this paper is to summarize Intels vision siliconinzing photonics, aims to
provide inexpensive silicon building blocks that can be integrated to produce optical products
that solve todays communication problem, and paper highlights the individual photonics
components used to develop integrated optical chip. A brief discussion of the components
such as silicon optical laser, silicon modulator, Si waveguide, Si optical detector, given first,
this is followed by Intels 50Gbps silicon photonic link.
