Polarization controlled quantum dashes (QDHs) VCSEL grown on InP are investigated. Using optimized growth conditions, QDHs are obtained, presenting a polarized photoluminescence at 1.55 µm at room temperature, following the [1-10] direction according to QDH length. VCSEL polarized output laser emission is demonstrated at room temperature. Output VCSEL polarization is oriented following the [1-10] direction, the extinction ratio is as high as 30 dB. Confrontation between QDH and QW VCSEL show improved performances for QDH VCSEL, in terms of polarization stability (static and dynamic) and polarization extinction ratio.
