Assessment of VCSEL Semiconductor Technology for Serial Usage in the Automobile (Technology Assessment)

Task:

Assessment of VCSEL (Vertical Cavity Surface Emitting Laser Diode) Technology for use in future optical automotive Gigabit networks

Content:

  • Benchmarking of VCSEL components from three different manufacturers
  • Definition of the mission profile, based on specific conditions in the intended vehicle installation section
  • Consideration of environmental conditions in the automotive field, e.g. temperature, operation duration, voltage, stress, etc.
  • Coordinated planning of the measures required for validation, in cooperation with the manufacturers of the VCSEL components
  • Investigation and evaluation of the reliability data, as it relates to deterioration failures and failure mechanisms within the defined life span
  • Comparison of the ascertained data versus the reliability requirements of the automotive industry.

Result:

Complete and positive assessment of the VCSEL technology through the verification of compliance to all requirements in the automotive field, following the defined measurements
