LEDs with emission centered at wavelengths  = 2.8 and 3.5 µm have been studied. In both cases, in the frequency range 2 ≤ f ≤ 100 Hz the noise spectrum is 1/f like. At constant LED pumping current, Slph is proportional to the photocurrent squared (~ Iph2). The 1/f noise intensity Slph for the LED with emission centered at  = 2.8 µm is ~2 times higher. In the LED pumping current range 0.02  ILED  0.1 A (60  jLED  300 A/cm2) the optical output 1/f noise is practically independent of ILED. The intensity of the LEDs’ optical output 1/f noise is less than the intensity of the photodiode reverse bias current noise by ~4 orders of magnitude. %G English %Z IRP TeraMIR %L hal-04104595 %U https://hal.science/hal-04104595 %~ CNRS %~ L2C %~ UNIV-MONTPELLIER %~ UM-2015-2021 %~ UM-EPE
