Uusimaa Vertical-cavity surface-emitting lasers (VCSELs) have recently paved their way into the 3D sensing market, specifically in mobile device applications. Vertical emission of VCSELs enables arranging single emitters into high-power 2D arrays. Thus, VCSEL arrays require efficient heat management which can be implemented by the means of packaging, both to improve thermal conductivity and to keep VCSEL chips intact. This becomes particularly important when considering also very high-density laser arrays and 2D matrices for quantum Continue reading →

The main commercial success area has been the printing industry and more recently digital press. These laser arrays are typically working at 8xx nm and 9xx nm wavelengths1,2 . Individually addressable laser diode arrays operating in visible region has also been reported3,4. There is an increasing interest in different variants of individual addressable arrays not Continue reading →

These laser arrays are typically working at 8xx nm and 9xx nm wavelengths. Individually addressable laser diode arrays operating in visible region has been less reported and especially with limited commercial success. Yet, there is increasing interest in different variants of visible laser arrays not only in printing industry, but also in various display applications Continue reading →
