Polarizing Large-Mode-Area Fibers
Our large mode area polarizing photonic crystal fibers add polarization filtering
capability to our range of large mode area fibers. The polarizing performance
is achieved via stress rod applied birefringence and a precisely controlled
index profile and enables polarized light high power transmission and filtering
without nonlinear effects or material damage.
The fibers can be spliced to standard PM fibers or directly connectorized
with standard FC/PC connectors or SMA 905 high power connectors.
The unique combination of stress-induced birefringence and our LMA structure
gives the widest polarization bandwidth in the industry where single polarization
guiding over several hundred nanometers is routinely achieved (see example
below).
The fibers will act as a traditional large mode area PM fiber for wavelengths longer than the polarizing cut-off.
The fibers are also available as patch-cords with hermetically sealed ends
and FC/PC connectors. For a connectorized fiber, we can customize the amount
of fiber end beam expansion.
