Large Mode Area photonic crystal fibers – Polarization-Maintaining
Our Large Mode Area photonic crystal fibers are designed for diffraction-limited high-power delivery. The large mode area prevents nonlinear effects and material damage.
With standard fibers, you trade large mode areas for single-mode operation. With our Large Mode Area PM fibers, you get single-mode, polarization-maintaining operation in a wide range of wavelengths.
Our LMA polarization-maintaining single-mode fibers are optimized for low loss and an almost constant mode field diameter. With standard technology, you trade large mode areas for single-mode operation. Our crystal fiber Large Mode Area polarization-maintaining fibers are endlessly single-mode (i.e. it has no higher-order mode cut-off) and deliver excellent mode quality at all wavelengths.
The PM-1550 has a strong form-birefringence and is optimized to create a short beat length between the polarizations. It has a reduced bend-coupling between polarization states, improved polarization extinction ratio, and is 30 times less temperature-sensitive than conventional high-birefringence fiber.
The LMA fibers are available in polarizing and polarization-maintaining versions.
