Current modulation/optical injection and feedback for semiconductor laser diode based on optical field rate and intensity rate equation model
摘要
This paper demonstrated the current modulation/optical injection and feedback for seminconductor laser diode based on optical field rate and intensity rate equation model. The injected electrical current and carrier density equations model are used to estimate the laser net gain, stimulated emission gain and spontaneous laser emission absorption. As well as the photon density equations model to determine the laser diode cavity loss and laser output power. The laser rate equations are clarified for the photon/electron concentration with the time. The small and large signal modulation response is demonstrated. The single mode laser diode equation for the complex optical field is studied. Laser diode output power is studied against laser pump current for both stimulated/spontaneous emission at first/second/third wavelength window. Laser relaxation oscillation frequency and optical gain are both clarified versus laser pump power for both stimulated/spontaneous emission at various wavelength window.
