ABSTRACT:
An optical amplifier having an optical multiplexer for WDM(wavelength-division multiplexing). The optical multiplexer has a plurality of input ports and at least one output port. Optical signals having different wavelengths are respectively supplied to the input ports. A plurality of feedback loops are used to respectively control the powers of the optical signals constant. The feedback loops are respectively operatively connected to the input ports of the optical multiplexer. An optical amplifier unit is operatively connected to the output port of the optical multiplexer. The optical amplifier unit has a gain band including the wavelengths of the optical signals. By using such feedback loops, an input dynamic range for each optical signal can be widened.
