Abstract :

It was observed that saturation of absorption and gain in As/GaAs self-assembled quantum dots with a continuous-wave (cw), home-made chromium: Fosferite (Cr4+: Fr) laser that can deliver power up to 100 mW in the 1.24-1.28 μm range. The saturation, depending on wavelength detuning is observed for Isat= (1.4-4.5) � 109 W/m2 in absorption and Isat=(0.2-3.8)�109 W/m2 in gain.
