These 2x2 Polarization Maintaining (PM) Fiber Couplers are designed for use from 460-2200 nm with selectable coupling ratios of 50:50, 75:25, 90:10, or 99:1. The 2x2 couplers are bidirectional and can be used to split and mix signals (see the 2x2 Coupling Examples tab). PM couplers are manufactured using Panda-type PM fiber, so they maintain a high polarization extinction ratio (PER) when light is launched along the slow axis of the fiber. As shown in the figure to the right, stress rods are parallel to the fiber core and apply stress, creating birefringence in the fiber core, resulting in PM operation. Typical applications for PM couplers include optical sensors, optical amplifiers, and fiber gyroscopes.

The default alignment mode of Idealphotonics' optical polarization-maintaining components is slow-axis alignment.
Idealphotonics' polarization-maintaining couplers have high extinction ratios and operate over a wide temperature range of -40 °C to 85 °C. Note that PER varies with temperature; see the Temperature Cycling Test Section in the Polarization Extinction Ratio Measurement tab for details. They have a max. power of 1 W with connectors or bare fiber and 5 W when spliced (see the Damage Threshold tab for details). These couplers have been extensively tested and PER verified; see the Polarization Extinction Ratio Measurement tab for details of the testing process.
Standard couplers feature 2.0 mm narrow key FC/PC or FC/APC connectors as summarized in the table below. When using the coupler as a beam combiner, it is necessary to terminate the fiber to the unused output, as some of the light will propagate through this branch. Fiber pigtails have Ø900 µm Hytrel® jackets and are 0.8 m long. Custom coupler configurations with other wavelengths, fiber types, coupling ratios, alignment axes, or port configurations are also available.

Note:
1. All test results do not include connectors. Adding connectors will increase the loss by 0.3dB.
2. We can accept customization for better parameters or other requirements.
3. If you need customized wavelength, coupling ratio and connector options.
