Stimulated emission of plasmon-LO mode in narrow gap HgTe/CdHgTe quantum wells
نویسندگان
چکیده
We calculate the dispersion of plasmon-LO modes taking into account spatial electronic polarizability. It is shown that stimulated emission mode possible in frequency range corresponding to Reststrahlen band GaAs both a 6 nm wide HgTe/CdTe QW and 5 HgTe/Cd0.7Hg0.3Te grown on (013) plane. Due anisotropy law for mode, [03-1] direction appears be optimal generation.

Low-threshold stimulated emission using colloidal quantum wells.
The use of colloidal semiconductor nanocrystals for optical amplification and lasing has been limited by the need for high input power densities. Here we show that colloidal nanoplatelets produce amplified spontaneous emission with thresholds as low as 6 μJ/cm(2) and gain as high as 600 cm(-1), both a significant improvement over colloidal nanocrystals; in addition, gain saturation occurs at pu...
متن کاملEnergy spectrum, density of states and optical transitions in strongly biased narrow-gap quantum wells
We study theoretically the effect of an electric field on the electron states and far-infrared optical properties in narrow-gap lead salt quantum wells. The electron states are described by a two-band Hamiltonian. An application of a strong electric field across the well allows the control of the energy gap between the two-dimensional (2D) states in a wide range. A sufficiently strong electric ...

متن کاملMagnetophotoluminescence of negatively charged excitons in narrow quantum wells
We present the results of photoluminescence experiments on the negatively charged exciton X in GaAs/AlxGa12xAs quantum wells ~QW! in high magnetic fields (< 50 T). Three different QW widths are used here: 100, 120, and 150 Å. All optically allowed transitions of X are observed, enabling us to experimentally verify its energy-level diagram. All samples behave consistently with this diagram. We h...
متن کاملSurface plasmon amplification by stimulated emission of radiation: quantum generation of coherent surface plasmons in nanosystems.
We make a step towards quantum nanoplasmonics: surface plasmon fields of a nanosystem are quantized and their stimulated emission is considered. We introduce a quantum generator for surface plasmon quanta and consider the phenomenon of surface plasmon amplification by stimulated emission of radiation (spaser). Spaser generates temporally coherent high-intensity fields of selected surface plasmo...
