Self-Consistent Approach for Calculation of VCSEL Spectra Under Deep Microwave Current Modulation
We develop a self-consistent approach to calculate the spectra of the vertical-cavity surface-emitting lasers under a deep microwave modulation of the injection current. The treatment consists of solving a coupled system of equations for the concentration of electrons in the active medium and those for the amplitudes of spectral components derived from Maxwell’s equations. Their numerical solution demonstrates the specific asymmetry of experimental laser spectra under microwave modulation of the injection current. The presented method also accounts for the simultaneous modulation at multiple frequencies. We demonstrate that the laser spectrum can be controlled to some extent, namely, its carrier can be suppressed and the ratio of the first sidebands powers can be simultaneously changed by additional modulation of the injection current at doubled frequency. In addition, we show that the phase difference of these components is stable under variations of modulation parameters in a relatively wide range.
期刊介绍:
The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
