A vertical cavity surface emitting laser (VCSEL) (40) having strain or stress elements (41) added for stable polarization control. The elements may disturb the symmetrical stress of the VCSEL structure to induce stable polarization control of its output. Such elements may be attached to the top surface or the sides of the VCSEL (40), or may be inserted in some of the layers of the VCSEL (40) structure. Some elements may involve the removal of material from the sides of the VCSEL (40). |
