Jm. Liu et Tb. Simpson, CHARACTERIZATION OF FUNDAMENTAL PARAMETERS OF A SEMICONDUCTOR-LASER WITH AN INJECTED OPTICAL PROBE, IEEE photonics technology letters, 5(4), 1993, pp. 380-382
A simple technique using a direct optical probe is demonstrated for pa
rasitic-free characterization of many intrinsic laser parameters, incl
uding the relaxation resonance frequency, the relaxation rate, the dif
ferential and nonlinear gain parameters, the linewidth enhancement fac
tor, and the carrier and photon lifetimes. It consists of a single exp
erimental setup and is broadly applicable to semiconductor lasers of d
ifferent wavelengths and different dynamic bandwidths.
