Abstract
PURPOSE:To make the intensity of saturation power large and obtain excellent noise characteristics by causing an active layer to contain an n-type-doped quantum well structure. CONSTITUTION:An active layer 4 contains an n-type-doped quantum well structure. Tip spherical fibers 21a and 21b are used to connect the active layer 4 to incident lights and also take out light signals and forward bias is impressed between electrodes 11 and 12, so that the gain in the active layer 4 rises to obtain amplification function. In such a case, the resultant n-type-doped quantum well structure in the active layer makes the intensity of saturation power high and enables this device to obtain an LD light amplifier having excellent noise characteristics. Furthermore, the quantum well structure makes the efficiency of a carrier density for an inputted current high and makes it possible to operate the amplifier with a low-voltage current.
