This paper is devoted to the evaluation of the transient performance as well as testing the stability of a new version of optoelectronic integrated devices. This version is composed of a resonant cavity enhanced heterojunction phototransistor and a light-emitting diode. It will be called as a resonant cavity enhanced optoelectronic integrated device. The evaluation of its transient response is based on the frequency response of the constituent elements and the optical feedback inside the device. Analytical expressions describing the transient behavior are derived. The numerical results show that the transient performance of the version under consideration strongly depends on the optical feedback inside the device and it has a very high optical gain in comparison with the conventional types. In addition, the possibility of operating the new device in two distinct modes is also available as similar to conventional types. Moreover, testing the stability of the new version demonstrates that its optical gain is stable as long as the value of the optical feedback is maintained below threshold value, while exhibits instability for values of optical feedback, which is greater or equal to this threshold value. |
