Paper Abstract

Nonlinear characteristics of laser diodes have very significant impact on applicability of high-speed fiberoptical communication systems. Large-signal modulation dynamics of laser diodes with (asymmetric) and without (symmetric) back facet reflective coating are theoretically and experimentally presented. Comparison of asymmetric and symmetric lasers in terms of harmonics and two-tone intermodulation distortion indicates that the former is best for data transmission whereas the latter is best suited for distribution of frequency reference, which is used for optical injection locking of oscillators.
