Spin Polarization Modulation Responses of Polarization Bistable VCSELs

Year: 2025

Type: article

Abstract: This study investigates the spin polarization modulation responses of vertical-cavity surface-emitting lasers (VCSELs) through numerical simulations and experimental measurements. The study employs the spin-flip model and optical spin polarization modulation technique, focusing on polarization bistability of VCSELs. Results indicate that the effective values of birefringence and dichroism—both dependent on the injection current of the VCSEL—influence spin polarization modulation responses. These findings suggest that polarization bistable VCSELs exhibit switchable spin polarization modulation characteristics that depend on the lasing polarization state. The observed results provide new insight into the application of spin-controlled VCSELs with polarization bistability.
