High Power C plus L Wave Band Er-doped Optical Fiber Photosource Design and Experiment

In order to obtain one kind of high performance C+L wave band wide band er-doped optical fiber photosource, through uses 980nm and a 1480nm light emitting diode takes the pumping source, with two 3dB wide band coupler took the optical fiber reflector, simultaneously lets the photosource output light using the power control circuit be stable, has carried on the experiment and the theory confirmation to the design photosource, has obtained the power is 168.67mW (22.27 dBm), the band width achieves 80.701 nm(1525.112-1605.813nm) C+L wave band wide band photosource. The result indicated that, starts experimental two 980nm and a 1480nm diode takes the pumping source, afterwards changes 980nm and a 1480nm diode takes the pumping source, has not reduced the photosource the output, also has not changed the stability. This result to reduces the photosource the cost, enhanced the smooth transformed efficiency to have the actual value.
