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.
Our Erbium Doped Waveguide technology can be found in:
With our erbium doped waveguide technology, we have realised:
