High-power VCSEL systems and applications

Abstract: Easy system design, compactness and a uniform power distribution define the basic advantages of high power VCSEL systems. Full addressability in space and time add new dimensions for optimization and enable "digital photonic production". Many thermal processes benefit from the improved control i.e. heat is applied exactly where and when it is needed. The compact VCSEL systems can be integrated into most manufacturing equipment, replacing batch processes using large furnaces and reducing energy consumption. Thi… Show more

“…In addition, infrared VCSEL arrays delivering power densities over 100 W/cm 2 are used for industrial heating. 2 The VCSEL market will be further expanded when visible-emitting GaN-based VCSELs are commercialized. This will soon be a reality based on the recent immense improvement in performance 3 8 enabled by advances in thermal management, 3 , 6 , 9 optical confinement, 5 , 10 , 11 mirror reflectivity, 8 , 10 , 12 and electrical injection.…”

“…As pointed out by key technology players, 92 it is likely that future smartphones will host onboard many VCSELs for increased interactions with the environment and the people. Next-gen TD systems could be easily produced as smart all-integrated microelectronic devices using standard technologies or exploiting low-cost production of standard telecom components (e.g., VCSELs).…”

“…With various advantages such as low cost and low power consumptions, VCSEL has been a key light source in short-reach optical communication systems [1,2,3,4,5]. As technology matures, VCSEL applications diversified including laser mice, printers, medical imaging and so on [6,7,8,9,10,11]. In recent years, VCSEL technology for 3D sensing has been attracting more and more interests [12,13,14,15,16].…”
