For fabricating HiBi fused taper Couplers
Fibercore’s PM Coupler Fiber (HB-C) is specifically
designed to optimize the performance of PM fused
taper couplers.
Through optimization of the ‘Bow-Tie’ design, the Stress Applying Parts
(SAPs) are engineered to minimize interaction between the mode field
and the stress applying parts within the tapered region.
For the fiber laser and sensor industry, using wavelengths around
1060nm, Fibercore offers two variants of fiber: HB1000C(6/125) with a
6μm Mode Field Diameter (MFD) and HB1000C(10/125) with a 10μm
MFD. The larger MFD variant gives significant benefits in power handling
capabilities and higher non-linear thresholds.
For applications requiring small package sizes, for example, the Fiber
Optic Gyroscopes (FOGs), the HB800C and HB1500C are bend
insensitive fibers with their cladding diameter optimized
designed to optimize the performance of PM fused
taper couplers.
