A 1550 (nm) emitting LED has an active region that is doped p-type with 1017 (cm-3) acceptors and a nonradiative lifetime of 50 (ns). At a forward current through the LED of 50 (mA) the voltage across the LED is 1.1 (V) and the emitted optical power is 4 (mW). For this LED, B = 10-16 (m3s-1). Calculate the following: a. Internal quantum efficiency b. External quantum efficiency c. Power conversion efficiency d. The light extraction efficiency
