1. Consider a commercial power laser diode with an emission wavelength of 730nm. The threshold current when diode is operated at 30°C is 20 mA. The typical operating voltage for this device is 2V. At I = 100 mA. The output optical power is 60 mW. (a) Calculate the External Quantum Efficiency (MEQE), External Power Efficiency (MPCE), slope efficiency (nslope) of the laser diode. (b) What is the current required for an output optical power of 100 mW? (Hint: use nslope)
