A double heterojunction InGaAsP LED emitting at a peak wavelength of 1310 nm has radiative and nonradiative recombination times of 25 and 90 ns, respectively. The drive current is 35 mA.
a) Find the internal quantum efficiency and the internal power level.
b) If the refractive index of the light source material is n = 3.5, find the power emitted from the device.
