We are pleased to announce the partnership between LASER COMPONENTS (UK) Ltd., and iXFiber with the supply of their speciality optical fibre.
In this article we focus on polarisation maintaining (PM) fibre, the PZ series, which is designed such that only one state of polarisation is guided along the fibre. Any other state of polarisation will be lost rapidly thus yielding a high built-in polarisation extinction ratio. This particular mechanism is obtained through a specific waveguide design and a careful optimisation of the glass composition resulting in both high birefringence and leakage behaviour.
PZ fibres are available at different wavelengths with a broad polarising window (typically larger than 100 nm), low attenuation and high extinction ratio (≥30 dB), that can be tuned by coiling the correct fibre length at the appropriate coil diameter. Contrary to in-line polarisers, the PZ fibre based polariser is an ‘all-fibre’ solution offering superior polarisation extinction ratio, low loss and excellent stability over temperature. iXFiber is also offering customised solutions including connectors, patch-cords and cables.
