10:90 2x2 1550nm Polarization-mode Fiber Coupler

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.

980nm Single Mode Fiber Reflector Mirror

An example of a fiber total reflector used in an erbium-doped fiber amplifier. In this example, a fiber retroreflector is placed at the end of an erbium-doped fiber to reflect light back into the fiber in the direction of the incident light. A circulator is used to directly guide the input light and the amplified output light into their appropriate optical paths, so that the signal light can pass through the gain fiber twice, and the gain of the amplifier is absorbed and utilized more effectively. Another practical application of retroreflectors is to build adjustable retroreflectors, as shown in Figure 2. The feedback signal from the downstream retroreflector can cause instability in some devices, such as laser diodes. By using an adjustable retroreflector, the sensitivity of the device to retroreflection can be determined. The adjustable attenuator allows the user to introduce standard reflections into the device. By analyzing the retroreflection effect, the user can calculate the device's noise level, bit error rate, distortion and other parameters.
