| Popis: | The structure of combining two segments of erbium-doped fiber (EDF) together—one EDF acting as an amplifier and the other as an absorber—has a special gain characteristic curve which has a maximum gain with an increase in the input signal power. This special gain characteristic curve can lead to an optical bistability (OB) phenomenon in a fiber-ring laser employing an EDF of this structure. By adjusting the pump light power injected into the second segment of the EDF, we can change the behavior of the absorber and can, therefore, control the range of the bistability region. A method is proposed to calculate the tunable optical bistability, and the calculation result is in accordance with our experiment. |
