Abstract: | In-phase wavelength conversion based on cross-gain modulation in a semiconductor optical amplifier biased around critical threshold current has been demonstrated. The converted signal and the pump signal have the same bit sequence 1101011000. The stimulated emission competition between the amplification of input signals and the amplified spontaneous emission was used to illustrate the conversion mechanism. Experiment results showed that in-phase wavelength conversion can be achieved with simple structure and high output extinction ratio. |
