The F-916 Polarization Maintaining Fiber Coupler offers efficient single-mode coupling of a laser beam into a bare PM optical fiber. Compared to F-915, this coupler adds a rotatable chuck mount for orienting polarization-preserving fibers. It provides the sub-micron positioning resolution necessary for high single-mode coupling efficiency. Fine translation and focus, required to position the focused laser beam on the fiber end face, are provided by the three-axis positioner that holds the fiber chuck — high-resolution 100 TPI adjustment screws for smooth XY adjustment and a knurled knob with 80 TPI thread for axial Z motion. Sub-micron resolution, required to optimize coupling to single-mode fibers, is provided by the kinematic tip and tilt stage that also uses 100 TPI adjustment screws to pivot the lens/fiber-holder assembly. Unlike conventional couplers, in which positioner runouts can exceed fiber misalignment tolerances, the fine-tuning tilt adjustments only introduce a second order translation of the beam. The couplers» optical axis height is fixed at a nominal 3 inch (75 mm), and they have a pattern of tapped and clearance holes in their base for convenient mounting on Newport tables and breadboards. Microscope objective and fiber chuck are sold separately.
