Fiber-To-Chip coupler

 

 

Taillaert et al., Jap. J. App. Phys. 45, 2006

The grating coupler couples light from an optical fiber to a photonic integrated circuit (PIC) and viceversa.
The working principle is based on the constructive interference, at a given angle, of the light diffracted by a grating, generally created by periodically alternating waveguides (WGs) with different thicknesses and lengths.
For deployment in applications requiring large bandwidth coupling from a fiber or a fiber array to a PIC and viceversa.

Specifications

  • Broadband
  • Coupling efficiency up to – 3 dB
  • Compatible with Mid-IR fibers around 3.4 um – fiber MFD ~ 10.6 um

Ongoing

  • Improving insertion loss performance and exploring designs at other WLs
