Michelson Interferometer Displacement Sensor


Based on its Photonics Integrated Circuits (PIC) technology, Teem Photonics can design and realize different types of Michelson (as well as Mach-Zehnder or Sagnac) interferometer circuits.

Thanks to our flexible integration technology, we can uniquely combine various optical functions to create compact, robust and reliable optical interferometer circuits.
