Laser Components also has multi-mode fibres and special fibres, such as, for example, sapphire fibres and hollow-core fibres available. In addition to these fibres, POFs and cables for applications with special requirements are also available.
Indoor and outdoor fibre optic cables are available in different designs. The SI200/230 optical fibre with a numerical aperture of 0.37 is the standard used in fibre optic cables. Depending on the customer’s requirements, other combinations are also available.
Used for maintaining the polarization of light within a fibre optic cable.
Polarizing (PZ) fibre is designed such that only one state of polarization is guided along the fibre; any other state of polarization will be lost rapidly thus yielding a high built-in polarization extinction ratio. This particular mechanism is obtained through a specific waveguide design and a careful optimization of the glass composition resulting in both high birefringence and leakage behavior.
PZ fibres are available at different wavelengths with a broad polarizing window (typically larger than 100 nm), low attenuation and high extinction ratio (≥30 dB), that can be tuned by coiling the proper fibre length at the appropriate coil diameter. Contrary to in-line polarisers, the PZ fibre based polariser is an All-Fibre solution offering superior polarization extinction ratio, low loss and excellent stability over temperature.
