摘要：

A quantum-dot semiconductor optical amplifier (QD-SOA) has the characteristics of picosecond gain recovery time and ultrafast carrier concentration recovery. The combination of photonic crystal (PC) and QD-SOA has the advantages of strong nonlinear effect, less absorption loss, high power transmission, and low power consumption. The wavelength conversion characteristics of photonic crystal-quantum dot semiconductor optical amplifiers (PC-QDSOAs) are studied, the influences of maximum mode gain, pumping power, detecting power, and active region length on the Q-factor of PC-QDSOA wavelength conversion are analyzed, and the relationships among the injection current, pumping power, detecting power, active region length, and extinction ratio of PC-QDSOA wavelength conversion are analyzed in detail. The simulation results of QD-SOA and PC-QDSOA are compared. The results show that the values of Q-factor and extinction ratio of PC-QDSOA are greater that that of QD-SOA, which indicates that the output signal quality, signal transmission efficiency, and conversion performance of PC-QDSOA are better than that of QD-SOA. The research results have guiding significance for the application of PC-QDSOA. © 2022, Chinese Lasers Press. All right reserved.
