VCSELs Market : Applications, Technology Trends, Growth Drivers and Challenges – Semiconductor & Electronics Industry Insights
VCSELs offer reliability, high precision and efficiency in optical sensors based on scattering, transmission, absorption, self-mixing, reflection, interference, and others. For instance, VCSELs are universal in applications using reflective sensors and scattering or imaging techniques to perceive objects or moving objects. Greater precision has increased the adoption of VCSELs in medical applications, such as medical diagnostics and therapeutics, optical nerve stimulation, computed radiography imaging. Multi-element VCSEL arrays offers around 1 W of CW optical power, low facet power density while providing high wallplug efficiency. Owing to this, various applications including LiDAR, aerospace, night vision, illumination, and line-of-sight communication links operating at 3 Gbps and higher have observed increase in demand of VCSELs. Proximity is measured by transmitting light and sensing reflections from nearby objects. Superior power efficiency over LEDs has increase the adoption of VCSELs in proximity sensing applications, which is further fueling the growth of the market.
