Based on the rate equations describing the dynamic characteristics of the master and slave vertical cavity surface emitting laser M-VCSELS-VCSEL, under the modulation of pulsed bias currentthe polarization characteristics of M-VCSEL output and the polarization switching performance of S-VCSEL subjected to optical pulse output from the M-VCSEL have been investigated. The results show that periodical pulses can be obtained by adding a periodical pulsed current on the M-VCSEL. Under injection of the optical pulsed from M-VCSEL, the output power of S-VCSEL will switch periodically between two orthogonal polarizationsand the period is equal to the period of the modulated current in M-VCSEL. Through changing the modulated amplitude of current in M-VCSELthe orthogonal polarization suppression ratio OPSR can be controlled easily.
