Paper Abstract

Large-signal modulation of a laser diode generates harmonics which can be exploited in applications such as indirect optical injection locking of millimeter wave local oscillators in optically controlled phased array antennas. Under large-signal modulation, the output harmonic content of laser diodes with and without reflective coating on the back facet is analyzed on the basis of the rate equations and is compared with the experimental results over 2-6 GHz. The utilization of these harmonics in the optical injection locking of millimeter wave oscillators has also been demonstrated for two 21.5GHz free-running FET oscillators. Finally a comparison has been made between the laser diode and FET nonlinearities. Experiments reveal that the laser nonlinearity has a greater contribution to the locking range than that of the FET.
