Photonic Bandgap Microcavity Surface Emitting Electroluminescence Light Source

摘要

We demonstrate an electrically injected defect-mode photonic bandgap microcavity surface-emitting laser at room temperature. The lasing threshold is ～500 mA, with a spontaneous emission factor of 0.06, two orders larger than coventional lasers. Near- and far-field modal characteristics of the emission confirm lasing from the defect-related microcavity in the photonic bandgap crystal.
