Product description
A side-coupled multimode combiner for 2 µm, available in 1+1x1 and 2+1x1 configurations with a PM signal feed-through fiber and a PM dual clad output fiber. G&H proprietary manufacturing techniques allow the precise fusion of multimode pump fibers to a PM (polarization maintaining) signal feed-through fiber and a PM dual clad output fiber providing high coupling efficiency over a wide pump wavelength range.
G&H power combiners can be fabricated from a range of industry standard multimode fibers allowing ease of splicing to commercially available laser diodes. Custom options cover large mode area (LMA), large diameter (LDF) and Active signal feed-through fibers and are available on request.
