Background of 850nm High-Power LED

850nm high-power LED refers to a type of LED with a peak emission wavelength of 850nm. It is widely used in the field of optical communication, such as in the optical modules of data centers, 40G/100G Ethernet, and other fields. Compared with traditional 1310nm and 1550nm optical modules, 850nm high-power LED has the advantages of higher speed, lower cost, and smaller size, which has become the mainstream choice for optical communication systems in recent years.

Technology of 850nm High-Power LED

The production of 850nm high-power LED involves several key technologies, including epitaxial film growth, chip processing, and packaging technology.

Epitaxial Film Growth

Epitaxial film growth is the foundation of 850nm high-power LED production. The epitaxial film needs to have high crystal quality, low defect density, and suitable composition to ensure the performance of the LED. Currently, the mainstream epitaxial film growth technology includes metalorganic chemical vapor deposition (MOCVD) and molecular beam epitaxy (MBE).

Chip Processing

After epitaxial film growth, the next step is chip processing. The main processes include slicing, cleaving, and dicing. The quality of the chip directly affects the performance of the LED. In recent years, with the development of technology, the yield of high-quality chips has been significantly improved.

Package Technology

Package technology is another critical factor affecting the performance of 850nm high-power LED. The main packaging methods include flip-chip packaging and wire bonding packaging. Flip-chip packaging has the advantages of high heat dissipation, high light extraction efficiency, and small size, which is more suitable for high-power applications.
