Optical Injection Locking of Polarization Modes in VCSELs Emitting at 1.3 $\mu{\rm m}$ Wavelength

Injection locking of polarization modes of 1.3 μm wavelength vertical-cavity surface-emitting lasers (VCSELs) fabricated via wafer fusion is investigated. Maps of the injected modes in the frequency-power plane reveal the detailed response of the slave VCSEL to the optical injection, in agreement with numerical simulations of the system.
