An all-optical triode based on a tandem wavelength converter was realized in reflective InGaAsP-InP semiconductor optical amplifiers using the same 1551 nm wavelength for input, control and output. The output power ranged from 0 to 2mW when the average control power was varied from O to 0.3mW. Therefore, the output-input characteristics can be changed dynamically by low control powers. The output modulation degree was retained at around 90% over a wide control power range of 0.01-1mW. The dependence of the output modulation degree on the input signal frequency indicates that the device can be operated with an input signal frequency up to 5 GHz. Because of its characteristics, this device can become a key component in future all-optical signal processing.
