Abstract
An infrared detector including a reflection portion which transmits far- and middle-infrared rays and which reflects near-infrared and visible rays; a photo-current generating portion having a plurality of layered quantum dot structures in each of which electrons are excited by the far- and middle-infrared rays having passed through the reflection portion so as to generate photo-current; a light emitting portion having a plurality of layered quantum well structures into each of which electrons of the photo-current generated by the photo-current generating portion are injected and in each of which the electrons thus injected thereinto are recombined with holes so as to emit near-infrared and visible rays; and a photo-detecting portion which detects the near -infrared and visible rays emitted from the light emitting portion and which detects the near-infrared and visible rays emitted from the light emitting portion and then reflected by the reflection portion.
