The Ultra Low Ratio Tap Coupler splits a very small amount of light from a signal path to a tap port. Low tap ratios such as 0.1%, 0.01% or 0.001% enable the monitoring photodetector to operate without damage or saturation. It is suitable for very high optical power, its main application is in the monitoring of optical sources such as fiber lasers.

The Mode Field Adapter can effectively expand the mode field of single-mode fiber or LMA fiber, match the LP01 mode field of larger LMA fiber. Available for different fiber types.

The Cladding Power Stripper (CPS) is designed for efficiently stripping off residual cladding power, ASE and escaped core modes of double cladding fiber while preserving minimal degradation to signal power and beam quality.

The (1+1)×1 Multimode Pump & Signal Combiner enables highly efficient combining of the powers from 1 multimode pump diode and a signal beam from the signal fiber into a double clad output fiber. The Pump & Signal Combiner is also available for different fiber types.
