Ga 1-x Al x Sb avalanche photodiodes: Resonant impact ionization with very high ratio of ionization coefficients
TL;DR: In this paper, the authors measured the impact ionization coefficients α (electrons) and β (holes) with different composition and temperature and found a resonant enhancement of the hole ionization coefficient for x = 0.065 (300 K) where the ratio α/α exceeds values of 20.
Journal ArticleDOI
Wavelength dependence of gain saturation in GaAs lasers
TL;DR: In this article, it was shown that the wavelength dependence of the gain saturation is caused by the change of the chemical potential within the excited region due to the coupling of the carrier density with the photon density via the stimulated emission process.
