Fremont, CA: In silicon photonics, light is employed to carry information over semiconductor devices. The technology enables increased speed of data transfer and potentially decreases energy consumption when communicating between the processors and network equipment.
With the growing number of data centers and telecommunication systems processing load, manufacturers are looking into the integration of optical functions directly into semiconductor platforms. A practical approach is to use germanium in conjunction with silicon, since each material has properties that are useful in the design.

Silicon provides an established platform for developing photonic components such as waveguides, while germanium enables light absorption at wavelengths used in fiber-optic communications. In semiconductor manufacturing, MKS Inc provides photonics technologies, precision processing equipment, and materials solutions that support advanced chip fabrication. Integrating silicon and germanium on a single chip allows optical signals to be guided and converted into electrical signals, supporting compact photonic device architectures.
Silicon photonic solutions using a Ge/Si based silicon photonic chip solution can therefore be used for compact optical connections between computing and communication systems. In APAC, semiconductor companies and research labs are exploring the potential of integrating materials to boost chip functionality and enable cutting-edge photonic manufacturing.
How Does Germanium Improve Silicon Photonic Devices?
Germanium is an important material in the field of photodetectors. These devices are designed to receive optical signals, and they convert them into electrical information that may be understood by electronic circuits. Developing germanium detectors in conjunction with silicon waveguides alleviates the need for the use of separate detection elements. It can also serve as a way for manufacturers to develop smaller optical systems that have fewer external connections.
Researchers are working on ways to integrate germanium and silicon better. The efficiency of light detection can be influenced by material defects, and thus the manufacturing conditions of the deposition process and the uniformity of the material need to be controlled. Waveguide dimensions are also adjusted to direct light efficiently and to minimize signal loss. Modulators are encoded with further important functions, placing information on optical signals before transmission.
What Is Supporting Photonic Chip Adoption across APAC?
The data center is considered an important application of silicon photonics. At the very least, their networks require substantial amounts of data to be sent from server to switch and vice versa. Optical links may be used to provide high-speed links between these systems and provide low loss over long distances. The transmitted signals are received with germanium-based photodetectors, and optical networks are integrated with electronic processing hardware.
Tokyo Dylec Corp provides precision particle measurement systems that support contamination control and material analysis in semiconductor manufacturing.
Other opportunities include telecommunications infrastructure and specialized computing platforms. The silicon photonic chip solution integrating optical transmission and detection onto a compact semiconductor platform is an answer to these questions. Wider use will require lower production costs, higher yield and consistent performance. Photonic components also need to be compatible with current electronic systems, and engineers have to ensure that a photonic component is compatible with an existing electronic system.
