    摘要: A low-noise, high-gain optical image amplifier includes a multi-mode pump source that injects optical energy into an active fiber's inner cladding to excite the dopant ions in a 2-D array of doped cores and provide gain. The cores are arranged to sample and collect light from an image incident on one end of the fiber, amplify the light and output an amplified pixilated image at the other end of the fiber. The multi-core active fiber preserves the spatial pattern and spectrum of the incident image. The cores may be configured as single-mode cores to preserve phase information or multi-mode cores to scramble the phase information. It is often desirable for the gain to be approximately uniform across the 2-D array. This can be achieved by pumping uniformly doped cores into their respective saturation regions.

    摘要: Phosphate glass fibers are an attractive alternative to silica fibers because they can be co-doped with much higher concentrations of Yb and Er and exhibit a higher optical gain per unit length. However, in such fibers the absorption of the pump is high and heating effects caused by the pump laser can cause a significant change in refractive index. This problem is overcome with a phosphate glass composition that exhibits a temperature coefficient of refractive index &bgr;=dn/dT close to zero. This is achieved by avoiding alkali metal oxides in the glass composition and by adjusting the concentration of the network modifiers such as BaO.
