Paper Abstract

The electrically pumped InGaAsP/InP active microring has been theoretically analyzed and numerically simulated based on subsection model, with carrier rate equation and amplified spontaneous emission taken into account. After the subsection model is introduced in detail, the spectrum characteristics are numerically investigated. The simulation results show that spectrum characteristics will shift under different pump current and injected light power. The performances of an optical on/off switching utilizing pump-probe method based on InGaAsP/InP active microring are investigated. The results show that if we choose probe light off resonation initially, and pump light on resonation, only several hundred of microwatt power of pump light can realize the probe light on/off conversion. Such a potential will be applied in many other optical applications with ultra low power consumption. However, carrier lifetime will be the main factor restricting the characteristics of electrically pumped active microring due to the fact that the refractive index change is induced by carrier density change.
