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.
