Abstract
We present an experimental investigation of a multi-contact semiconductor optical amplifier. This first-generation
device allows for direct control of the carrier density profile along the length of the waveguide. This is used to
control the device noise figure, with a minimum value of 5 dB observed at a gain of 15 dB for an optimum carrier
density profile. The opposite carrier density profile results in an increase of the power saturation by 3 dB.
