| Abstract: | The relationship between laser cavity parameter and the injection current can be obtained based on input electrical power and outopt light power of Laser Diode(LD),then the limit equation of LD design,i.e.,the relationship between LD current and conversion factor of current gain,is given accordingly.The cavity length parameter is optimized according to the optimal point of the gain curve.It discusses fixed active cavity length,fixed inactive cavity length,fixed rate of the active cavity length and the inact... |
