Abstract

Recently, the polarization property of vertical-cavity surface-emitting lasers (VCSELs) has been investigated. It is found, however, that no polarization selection role is observed in planar isotropic devices except some trials introducing anisotropy^1,2 and much stronger polarization selectivity is needed for stable polarization operation. In this paper, we propose a novel polarization control method by a biréfringent laminated metal/dielectric polarizer³ terminating a distributed Bragg reflector (DBR) with adjusting the phase condition between two polarization states.
