Integrated two-pump combiner for optical fiber amplifiers
An integrated optical fiber amplifier system includes a non-reciprocal combination-device and an optical fiber amplifier. The non-reciprocal combination-device includes a first birefringent wedge, a second birefringent wedge, and a non-reciprocal rotating element. The optical fiber amplifier is optically coupled to the first birefringent wedge for receiving a combined pump light from the non-reciprocal combination-device.
