摘要: We report the observation of transverse electric polarized electroluminescence from InAs/AlInAs quantum dash cascade structures up to room temperature. The emission is attributed field confined along shortest lateral dimension dashes, as confirmed by its dependence on crystallographic orientation both in absorption measurements a dedicated sample and itself. From we estimate dipole moment for observed transition =1.7 nm. peaked at around 110 meV increases with applied bias. Its temperature shows decrease higher temperatures limited optical phonon emission.
