Polarization switching current of vertical cavity surface-emitting Lasers in an applied electric field

open access: yes, 2001
The polarization of vertical-cavity surface-emitting laser (VCSEL) can be controlled by electro-optic birefringence. We calculated the birefringence resulted from external electric field which was imposed on the top DBR of VCSEL by assuming that the two ...
