GlobalFoundries® Silicon Photonics - GF Fotonix™ (45SPCLO)


The GlobalFoundries® (GF) silicon photonics (SiPh) foundry portfolio is designed to help you deliver more data faster, farther, and more efficiently than traditional CMOS technologies. 45SPCLO, built on a 45 nm SOI platform, enables monolithic integration of RF, analog and Si-Photonic circuits with high efficiency and high data speed.

CMC Microsystems offers access to GlobalFoundries technologies via its cost-shared multi-project wafer runs.


The GF SiPh portfolio is optimized to help you take optical communications to the next level across a range of evolving and emerging applications:

  • 5G backhaul/front haul (1310/1550 nm wavelength)
  • Short reach, intra-data center (1310 nm wavelength)
  • Datacenter interconnect (1550 nm wavelength)
  • Chip-to-chip interconnect (1310 nm wavelength)
  • Metro telecom (1550 nm wavelength)
  • Long haul telecom (1550 nm wavelength)
  • Automotive Lidar, IoT, Cloud, AI, etc.


  • Monolithic integration of RF, analog and SiPh (45 nm SOI CMOS technology)
  • Minimum lithographic image of 40 nm (gate only)
  • Core Voltages: 0.9V, 1V
  • Ge EPI integration coupled into SOI WG
  • BEOL Metallization Stacks – 9 levels
