Problem 2) -
- Laser diode efficiency -
a) There are several laser diode efficiency definitions as followed: The
external quantum efficiency, MEQE, of a laser diode is defined as
Number of output photons from the diode (per unit second)
Number of injected electrons into diode (per unit second)
11 EQE
The external differential quantum efficiency, TEDQE, of a laser diode is defined as
Increase in the number of output photons from the diode (per unit second)
1 EDQE =
Increase of the number of injected electrons into diode (per unit second)
The external power efficiency, TEPE, of the laser diode is defined by
Optical output power
EPE =
Electrical input power
If Po is the emitted optical power, show that
