Abstract :
A negative feedback optical amplification effect was confirmed using negative feedback based on cross-gain modulation in semiconductor optical amplifiers. The optical amplifier was capable of providing an output signal whose gain is stabilized optically. In addition, an all-optical inverted triode was realized in the amplifier. The output-input characteristics can be changed dynamically by low control powers. Because of its characteristics, the device can become a key component in future all-optical signal processing.
