Electrically injected photonic crystal edge-emitting quantum-dot light source

An electrically injected photonic crystal (PC) edge-emitting light source with horizontally coupled waveguide, based on a GaAs heterostructure with self-organized InGaAs quantum dots emitting near 1 μm, is demonstrated. The emission spectra and near-field images indicate that the spontaneous emissio...

Summary:An electrically injected photonic crystal (PC) edge-emitting light source with horizontally coupled waveguide, based on a GaAs heterostructure with self-organized InGaAs quantum dots emitting near 1 μm, is demonstrated. The emission spectra and near-field images indicate that the spontaneous emission from the low-Q resonant PC cavity is coupled to an adjacent PC missing defect waveguide and guided over the 70-μm waveguide length.
