Blue vertical-cavity surface-emitting lasers (VCSELs) are strongly desired for many applications, including adaptive laser headlamps, retinal scanning displays, visible light communication systems, and processing of metals such as copper and gold. For many applications, high output powers and low-divergence output beams are preferred because they allow high efficiency fiber coupling and high optical density to be realized with very simple optics. This presentation will focus on recent progress in high power and mode control technologies of blue VCSELs and VCSEL arrays.
Masaru Kuramoto has over 25 years experience in developing and commercializing semiconductor lasers at NEC, SONY/Tohoku University (as a visiting associate professor), and Stanley Electric. He joined Stanley Electric in 2015 and started development of blue VCSELs in 2017. He received his BE/ME and Ph.D. degrees from Sophia University in 1992/1994 and 2004, respectively.
