Where traditional computer chips push electrons through copper wires, silicon photonic chips guide photons (particles of light) through tiny channels called waveguides etched into the same silicon material. The result is faster data transfer, less heat, and dramatically lower energy. This in-depth guide explores the fundamentals, principles, advantages, industry landscape, challenges, and future trends of silicon photonics. Definition of Silicon Photonics 2. Technical Advantages of Silicon. Silicon photonics—the technology of manufacturing the hundreds of components required for optical communications with CMOS processes—has been employed to produce coherent optical modules for metro and long-distance communications for years. It enables optical communication on a silicon platform, bringing together the speed of light with the scalability of CMOS. Optical modules have a wide range of applications, with access network optical modules accounting for less than 15% of the market, including PON modules for wired access and 5G fronthaul modules for wireless base stations. The silicon is usually patterned with sub-micrometre precision, into microphotonic components.
