Seoul Viosys Begins Mass Production of 25Gbps VCSELs for 5G Communication Applications

Seoul Viosys (KOSDAQ: 092190), a leading compound semiconductor provider, announced that for the first time in Korea, Seoul Viosys succeeded in developing vertical cavity surface emitting laser (VCSEL) technology, a near-field-only 25Gbps laser diode compatible with 5G wired networks for transmitting and receiving, and has started mass production to supply these products to three initial customers.

VCSEL is a laser diode technology that converts electrical signals into optical signals. It has recently attracted attention as a light-based communication technology that achieves ultra-high-speed data communication in 5G environments. This technology is necessary for AR/VR, 3D sensing and the camera-applied ToF (Time of Flight) for smartphones, and automotive LiDAR. Seoul Viosys’ VCSELs for sensor applications have already received customers’ approval and will be mass-produced within the first quarter of 2021, and the LiDAR technology is also undergoing the approval process to be supplied to an automotive system solution provider. According to the Yole Développement, a leading compound semiconductor research firm, the global VCSEL market is expected to grow 18.4% annually from $1.1B in 2020 to $2.7B in 2025.

The 25Gbps VCSEL developed by Seoul Viosys is a high-performance laser diode technology that emits light vertically from semiconductor substrates to enable fast communication. Currently, the 25Gbps VCSEL market has seen three large U.S. companies – II-VI, Lumentum, and Broadcom – involved in a power struggle for these high value-added products, which have more than 10 times of selling price that of LED. Seoul Viosys’ VCSEL can be implemented in a single channel or four-channel configurations, depending on its intended use, and the four-channel implementation features 100Gbps (4x) of high-capacity and high-quality data reception and transmission. Although the VCSEL technology exhibits a high degree of difficulty in implementation, it is expected to cover a wide range of applications in the future, as it is price competitive compared to horizontal-type laser diodes that emit light from the sides.

“As the paradigm shift has progressed in the recent noncontact era, interest in VCSEL technology is growing, since it is a critical technology for implementing the Internet of Things (IoT) environment. Seoul Viosys will continue to research and develop the VCSEL technology to expand and apply our differentiated VCSELs to 5G communication-based smart cities, autonomous driving applications, AR/VR, and industrial IoT markets,” said an official at Seoul Viosys.

About Seoul Viosys

Seoul Viosys is a full-line solution provider for UV LED, VCSEL (Vertical Cavity Surface Emitting Laser), the next-generation light source for 3D sensor and laser, and a single-pixel RGB “Micro Clean Pixel” for displays. Established in 2002 as a subsidiary of Seoul Semiconductor, it captured No. 1 market share in the UV LED industry (LEDinside, 2019). Seoul Viosys has an extensive UV LED portfolio with all wavelengths ranging from 200nm to 1600nm, including ultraviolet rays (UV), visible rays, and infrared rays. The company holds more than 4,000 patents related to UV LED technology. Violeds, its flagship UV LED technology, provides a wide range of industries with optimal solutions for robust sterilization and disinfection (UV-C), skin regeneration (UV-B), water/air purification and effective cultivation for horticulture. In 2018, Seoul Viosys acquired RayCan, a leading optoelectronic specialist, to add advanced VCSEL technology, which supports smartphone facial recognition and autonomous driving, and has started mass production. In January 2020, it introduced a disruptive “Micro Clean Pixel” that has the potential to be a game-changer in the display market. To learn more, visit http://www.seoulviosys.com/en/.
