Yb Fibers – Others
|
Coractive offers a selection of Yb-doped single-clad fibers as the different parameters can affect the desired amplification: wavelength emission, ASE and power threshold, nonlinear effect threshold. Moreover, these fibers have high resistance to photodarkening which enables excellent stability over time. |
|
Polarization-maintaining fibers
|
Polarization-maintaining (PM) fibers rely on the fact that an intentional birefringence introduced in the fiber will maintain two polarization modes that propagate along the fiber distinctly. In order to transmit this polarized light, a passive fiber with the same PM properties is needed.
Coractive develops a wide range of passive PM fibers that match their active fiber in order to minimize losses caused by mismatching.
