About This Webinar
3D sensor technology has developed into a ‘game-changer’ for smart products using vertical-cavity surface-emitting lasers (VCSELs) as efficient light sources. VCSEL-based sensor technology supports applications such as AI, internet-of-things (IoT) and AR/VR technologies; it also simplifies the integration of smart systems into our everyday chores. However, because VCSELs have special properties, their characterization is more complex than that of other typical laser sources.

In this presentation, Karthik Iyer guides attendees through:
  • Special aspects of VCSEL testing.
  • Challenges along the complete value chain.
  • How to establish a full VCSEL characterization.
  • Requirements of polarization control.
