A look back at OFC 2023

Gunther Roelkens presented at OFC conference 2023 recent demonstration of narrow-linewidth tunable laser through micro-transfer printing a prefabricated III-V gain section on imec’s 200-mm Si/SiN platform.

Key results:

  • Lasing in the C+L band
  • Linewidth below 3 kHz
  • The quality control of both the III-V and Si3N4 in their respective foundry is possible which creates path to high yield, by fabricating III-V and Si3N4 in separate, dedicated fabs

Results will be detailed in paper “III-V-on-silicon nitride narrow-linewidth tunable laser based on micro-transfer printing” which will be published in OPTICA and IEEE Digital library soon!
