Abstract :
We report the first experimental observation of periodic oscillations in an optically spin-injected GaInNAs/GaAs 1300 nm VCSEL under CW pumping and operated at room temperature. We show that the stability of the VCSEL can be controlled with the pump ellipticity. 11 GHz periodic oscillations were observed with the device subject to circularlypolarized (left or right) optical pumping. The highest RF oscillation power was found with elliptically-polarized pumping with P = ±0.6. The simulation results using the SFM were in very good agreement with the experiments.
