Single Mode Splitters, Miniature Size; 980 to 1550 nm; Splitting Ratio 50/50 to 98/2; Polarization Dependent Loss 0.1 dB; Directivity >50 dB OZ Optics’ FOBS-12N series of miniature polarizing (single mode) fiber optic beam splitters are used to split the light traveling through a fiber into two fibers, or to split or combine orthogonally polarized light into separate fibers. These splitters feature a rugged miniature housing to fit into compact spaces in equipment and systems. Light from a fiber is first collimated, then sent through a beam-splitting optic to divide it into two beams by either a fixed ratio or into two orthogonal polarizations. The resultant output beams are then coupled back into the output fibers. This flexible design allows splitters with different fiber types on the input and output ports. For example, light from a single mode fiber could be split into its two orthogonal states and then launched into two polarization maintaining fibers. Standard products for 1550 nm applications are readily available, while custom items can be made with rapid turnaround at low cost. Products for other wavelengths, such as 980 nm, 1300 nm, or 1480 nm are offered. Contact AMS Technologies for details and a quotation. The FOBS-N12 series of polarizing beam splitters split incoming light into two orthogonal states. They can also be used to combine the light from two fibers into a single output fiber. When used as a beam combiner, each input signal will transmit along a different output polarization axis. By default, the output fibers on a polarizing splitter are aligned so that the output polarization from each fiber is in line with the stress rods of the fibers. If the input fiber is a polarization maintaining (PM) fiber, the input fiber is aligned such that light polarized parallel to the fiber’s stress rods is transmitted to port 1 of the splitter, while light polarized perpendicular to the stress rods is transmitted to port 2 of the splitter.
