Introduction

Silicon photonics technology is a low-cost, high-speed optical communication technology based on silicon photonics. It uses laser beams instead of electronic signals to transmit data. Intel Labs realized silicon photonic-based data connections for the first time through integrated lasers with hybrid silicon laser technology. .

principle

Silicon photonics technology uses standard silicon to enable optical information transmission and reception between computers and other electronic devices. Unlike transistors, which rely mainly on ordinary silicon materials, the basic material used in silicon photonics technology is glass. Since light is transparent to glass and does not interfere, it is theoretically possible to transmit signals by integrating an optical waveguide in the glass, which is suitable for large-scale communication between a computer and a multi-core. The biggest advantage of silicon photonics technology is that it has a very high transfer rate, which enables data transfer between processor cores to be 100 times faster or higher.

R&D process

In 2006, Intel and the University of California, Santa Barbara successfully developed the world's first electronic hybrid silicon laser fabricated using standard silicon processes.

In 2008, Intel introduced the "Avalanche Silicon Laser Detector", which boosts the gain-bandwidth product of silicon photonics technology to 340 GHz.

Laser transmission

Laser transmission generally consists of two terminal stations and a relay station, which are made up of optical fibers. Each terminal station has an optical transceiver, wherein the function of the transmitting device is mainly to generate a laser, and convert the electrical signal into an optical signal, that is, electrical/optical conversion. The receiving device mainly performs light detection and amplification, and converts the optical signal into an electrical signal, that is, optical/electrical conversion. The relay station converts the received optical signal into an electrical signal, and after the decision regeneration process, converts the electrical signal into an optical signal for transmission.
