VCSEL technology, since its commercial availability in 1996, has been widely adopted in sectors such as data centers, consumer electronics, automotive, industrial, and healthcare among others. The major applications of VCSELs in these sectors are data communication and sensing. These two applications hold a very large share of the VCSEL market and are expected to further drive the demand in the coming years. Some of the other applications include infrared illumination, pumping, and industrial heating. Although the market penetration of VCSEL devices in these applications is presently very low, the demand is set to rise in the coming years.

The key revenue pockets for the VCSEL market are expected to be data communication and sensing applications in sectors such as the data centers, consumer electronics, and automotive. Data communication has always been the largest market for VCSELs as they offer reliable high-speed data transmission through optical fibers at low operating costs and reduced power consumption. The recent technological developments in multimode fibers (MMF) have led to increase in the data rates at which VCSEL devices can emit energy, thus making them an important technology in data centers.

VCSEL devices gained popularity in the sensing application as it was the core technology for optical mouse devices. These devices improved the point and click operations in GUI-based computers because of their high sensitivity, long operating life, and low power consumption. These devices effectively led to the exit of mechanical mouse devices from the market. Recent developments are enabling these devices to be used as 3D sensors for imaging and measurement purposes. These can prove to be extremely useful for gesture recognition and 3D imaging in home entertainment and gaming devices, car navigation systems, and computers used in industrial applications and medical laboratories. Gesture recognition and 3D sensing are expected to open additional growth opportunities and drive the overall VCSEL market across various industries.
