One Shot: Polarization Characterization of VCSELs


Date: 2022/01/11 – 2022/01/11

Location: Online

3D sensor technology has developed into a real “game changer” for smart products on the basis of VCSELs (vertical-cavity surface-emitting lasers) as an efficient light source. VCSEL-based sensor technology supports applications such as artificial intelligence (AI), Internet-of-things (IoT) or AR/VR technologies and simplifies their integration into our everyday chores. As VCSELs have special properties, in contrast to other typical laser sources, their characterization is more complex.


In this presentation, Karthik Iyer will guide you through:
1.    Special aspects of VCSEL testing
2.    Challenges along the complete value chain
3.    How to establish a full VCSEL characterization
4.    Need of polarization control
