Photonic Integrated Circuits (PICs)

Circuits of Light

PSI is a leader in developing integrated photonic technologies in support of Quantum Information and National Security

Key Features

We use a virtual foundry model, including a trusted vendor supply chain, to fabricate PICs in material systems such as  Silicon

  • Silicon Nitride
  • Thin-Film Lithium Niobate (TFLN)
  • Indium Phosphide

Where existing solutions are already optical, these optical circuits bring Size, Weight, Power, and Cost (SWaP-C) reduction. Where the existing solution is only electronic, these PICs enable new capabilities in application areas such as:

  • Photonics, Antenna Remoting
  • Q-bit multiplexing (time, frequency, etc.)
  • Beam conditioning and delivery for quantum sensors and free space
  • Chip-based Spectrometer
  • Optical Phased Array


Silicon Nitride PIC


  • Modulators (amplitude, phase)
  • Switches
  • Couplers (grating, tapered, etc.)
  • Frequency shifters and filters
  • Resonators
  • Polarizers
  • solators
  • Integrated Lasers
