Long-wave (10μm) infrared light emitting diode device performance

Effect of indium mole fraction on infrared light emitting diode (LED) device performance

“…Type‐II interband cascade (IC) electroluminescence in the 5–8‐µm spectral region from an LED structure was first reported by Yang et al 2. Recently, we reported the fabrication and operation of the LED arrays in the 3–4 and 8–10 µm in the MWIR and long wave infrared (LWIR) regions 3, 4, respectively. Gallium antimonide (GaSb)‐based IC LED structure recently emerges as potential IR light source for scene generation experiment.…”

Transmission, Reflection and Thermal Radiation of a Magneto-Optical Fabry-Perot Resonator in Magnetic Field: Investigations and Applications

“…The researchers pin their hopes on the quantum well based LEDs, which construction and composition makes possible to expand the radiation range to 8 10     m (Das et al, 2008;Yang et al, 1997) and even to create LED with two color spectral characteristic of emission (Das, 2010). However, the intensity of emission of such devices at room temperatures in LWIR does not exceed several  W.…”

Thermal emission of one-dimensional magnetophotonic crystals

“…While in the near-infrared (λ < 2 µm) light-emitting diodes (LEDs) are used successfully, in the mid-wave (MWIR) and long-wave IR (LWIR) ranges an external quantum efficiency still abruptly reduces their use. The quantum well based LEDs make it possible to expand the emission range to λ ≈ 8-10 µm [1,2] and even to create LEDs with two-color spectral emission characteristics [3]. However, the intensity of the emission of such devices at room temperatures in LWIR does not exceed several µW.…”
