a) The differential quantum efficiency of an InP laser is 30%. A
voltage of 2.5 V is applied over the component. Calculate the
external efficiency of the laser neglecting the losses inside the
cavity. b) The following parameters are known about the laser:
emission wavelength 850 nm, threshold current 12 mA, differential
quantum efficiency below threshold 2%, and differential quantum
efficiency above threshold 25%. Calculate the emitted power, when a
current of 18 mA flows through the laser.
