Erbium Doped Waveguide

Teem Photonics masters the realisation of waveguide-amplifier and waveguide-laser, based on its glass ion-exchange technology. We use for that erbium or ytterbium doped glasses.

Thanks to our flexible integration technology, we can uniquely combine passive and active optical functions to create compact, robust and reliable optical circuits, which serve many applications.

Serve a wide range of applications:

Our Erbium Doped Waveguide technology can be found in:

  • Optical communication components and systems
  • Laser source and laser systems 
  • Light sources for optical sensors
  • Avionic and naval industry
  • Defence and security

 

Example of realisations:

With our erbium doped waveguide technology, we have realised:

  • Planar Glass Laser (PGL) 1.55µm DFB waveguide laser, based on the combination of erbium doped waveguide and Bragg grating
