Application Examples: Planar Photonics Device Alignment and Test

AEi configured and delivered a PMAT station with required custom fixturing, tooling, instrumentation and process sequencing to align and test a series of different planar light chips (PLCs). These devices had very different geometries and sizes. The number of output channels also ranged from 8 to 40 or more.

Application Requirements:

  • Process prototyping
  • Interchangeable tooling
  • Vision guided pick and place of components from trays
  • Automated IMF dispense
  • Active alignment
  • Full device functional test

All test and process equipment was fully automated and integrated into the system. Three digital cameras performed a wide range of machine vision processes, including pick and place of components from trays as well as initial course alignment of devices to fibers. The machine vision incorporates pattern recognition for improved process reliability and repeatability.
