Опис
The InAsSbP/InAs light emitting diodes LEDs grown by liquid phase epitaxy and tuned at several
wavelengths inside the 3–5 mkm band were tested. Light pattern, radiation apparent temperature
Ta, thermal resistance, and self-heating details were characterized at T=300 K in microscale by
calibrated infrared cameras operating in the 3–5 and 8–12 mkm bands. The authors show that LEDs
dynamically simulate very hot Ta=750 K targets as well as cold objects and low observable. They
resume that low cost LEDs enable a platform for photonic scene projection devices able to compete
with thermal microemitter technology. Proposals on how to further increase LEDs performance are
given.
