Abstract

Sustained, large amplitude and tunable birefringenceinduced oscillations are obtained in a spin-vertical cavity surface-emitting laser (spin-VCSEL). Experimental evidence is provided using a spin-VCSEL operating at 1300 nm, under continuous-wave optical pumping and at room temperature. Numerical and stability analyses are performed to interpret the experiments and to identify the combined effects of pump ellipticity, spin relaxation rate, and cavity birefringence. Importantly, the frequency of the induced oscillations is determined by the device's birefringence rate, which can be tuned to very large values. This opens the path for ultrafast spin-lasers operating at record frequencies exceeding those possible in traditional semiconductor lasers and with ample expected impact in disparate disciplines (e.g., datacomms, spectroscopy).

Abstract

Polarization switching (PS) in 1550nm-VCSELs under single and double pulsed polarized optical injection is investigated experimentally and in theory. ‘Normal’ and ‘reverse’ PS were achieved, respectively, when the device was subject to single and double optical injection. Speed operation enhancement is observed for ‘reverse’ PS under double polarized optical injection. Also, the minimum injection power requirements for both ‘normal’ and ‘reverse’ PS have been analyzed showing significant differences for the two investigated cases. Furthermore, we have also investigated numerically the influence of important system parameters, such as the normalized bias current, the injection field strength and the linewidth enhancement factor in the optimal operation conditions for both types of PS. Overall good agreement between theory and experiments is found. Fil: Salvide, Matias. Universidad Nacional del Centro de la Provincia de Buenos Aires. Facultad de Ciencias Exactas.
