TL;DR: Simulations demonstrate that all previous interband cascade laser performance has suffered from a significant imbalance of electron and hole densities in the active wells, and confirm experimentally that correcting this imbalance with relatively heavy n-type doping in the electron injectors substantially reduces the threshold current and power densities relative to all earlier devices.

TL;DR: In this paper, the authors review the current status of interband cascade lasers (ICLs) emitting in the mid-wave infrared (IR) and discuss theoretical aspects of the active region and core designs, growth by molecular beam epitaxy, and the processing of broad-area, narrow-ridge, and distributed feedback (DFB) devices.

TL;DR: In this paper, the absolute photoluminescence (PL) quantum yield, φPL, was measured for a wide variety of organic compounds in solid films, pure and molecularly doped with strongly fluorescent materials.

TL;DR: In this paper, the emission mechanism in molecularly doped organic light-emitting diodes, where the emitting layer is composed of N,N'-diphenyl-N,N-,N'-bis(3-methylphenyl)-1,1'-biphensyl-4,4'-diamine (TPD) as the host and 5,6,11,12-tetraphenylnaphthacene (rubrene), as the dopant, is investigated in terms of energy transfer and direct carrier recombination.

TL;DR: In this paper, the first quantum cascade laser on silicon has been demonstrated, operating in pulsed mode at room temperature, emitting 4.8μm light, integrated with silicon on-nitride-on-insulator (SONOI) waveguides.
