The PM Combiner enables the efficient combination of two orthogonally polarised sources of light such that they are output through the same, single fibre output.
In optical amplifiers this provides a doubling of pump power whilst ensuring pump redundancy should a pump failure occur.
Applications include high power optical amplifiers and undersea systems. All ports consist of polarisation maintaining fibre.

Our TFB series Power Combiners provide a high efficiency means of combining light from several multimode sources into one fibre.
Our proprietary manufacturing techniques allow the precise fusion of input fibres around a central PM polarisation maintaining) signal feedthrough fibre and a PM dual clad output fibre providing high coupling efficiency over a wide pump wavelength range.
Available in standard 3x1 and 7x1configurations, our power combiners can be fabricated from a range of industry standard multimode fibres allowing ease of splicing to commercially available laser diodes.
Available in a standard (6+1)x1 configuration, the combiner can be fabricated from a range of industry standard fibres for ease of splicing to commercially available laser diodes and fibre applications.
Custom options cover large mode area (LMA) signal feedthrough fibres, dual clad output fibres and port count / configurations and are available on request.
Custom variants using non-standard fibres are available on request.

Our Visible Wavelength Combiners are singlemode optical fibre components and modules. They enable any two or three primary colours in the visible wavelength region to be combined or separated.
Designed for applications in display systems, sensors and biomedical equipment, the combiners utilise our low loss fused fibre technology.
No light leaves the fibre and therefore no alignment is required; and there are no unwanted reflections. Furthermore the output fibre pigtails may be directly integrated into beam delivery systems.
Combiners are available for either 2 or 3 wavelengths: 2 wavelength combiners combine red/green, blue/green or red/blue. 3 wavelength combiners provide full RGB operation; enabling full colour displays.
All variants are available on a custom basis, so please contact us to discuss your specific requirements.
