Cyj. Chu et H. Ghafourishiraz, A SIMPLE METHOD TO DETERMINE CARRIER RECOMBINATIONS IN A SEMICONDUCTOR-LASER OPTICAL AMPLIFIER, IEEE photonics technology letters, 5(10), 1993, pp. 1182-1185
The contribution of nonradiative carrier recombinations to the charact
eristics of long-wavelength InGaAsP/InP semiconductor laser devices is
verified by measuring the amplified spontaneous emission (ASE) power
from a 1.5-mum semiconductor laser amplifier (SLA) against the bias cu
rrent. This method provides a simple and straightforward way to determ
ine the mathematical form of recombination rate in a long-wave-length
semiconductor laser, provided that the structural parameters of the la
ser are known.
