Photonic Crystal Fiber

Our polarization-maintaining single-mode fibers, which are optimized to exhibit low loss while keeping an almost constant mode field diameter.

The fiber is endlessly single-mode (i.e. it has no higher order mode cut-off) and delivers excellent mode quality at all wavelengths.
