（レーザー関連）Faster rise and fall times for Time-of-Flight applications with Osram’s industry-changing multi-junction VCSEL

Osram’s 550 aperture PowerBoost Vertical Cavity Surface Emitting Laser (VCSEL) improves power conversion efficiency up to 60 percent.

• Osram Opto Semiconductors to unveil 550 aperture PowerBoost Vertical Cavity Surface Emitting Laser (VCSEL), along with other leading technologies at this year’s Photonics West.
• VCSELs emit light via individual apertures; combining several apertures in an array increases power without compromising efficiency.
• The 550 aperture offers the right amount of optical power to meet the demands of Time-of-Flight (ToF) applications, while keeping the chip size as small as possible.

Osram Opto Semiconductors strengthens its position as a leading player in the fast-growing VCSEL market with its PowerBoost multi-junction VCSEL product. VCSEL technology is making a huge impact in the 3D sensing market with its outstanding beam quality, simple design and compact size. The PowerBoost VCSEL improves power conversion efficiency up to 60 percent and enhances optical power. The product’s faster rise and fall times enable short pulse lengths, which are critical in ToF applications for reaching farther distance without compromising eye safety. VCSELs power many consumer applications, such as 3D cameras and facial recognition in mobile devices, as well as industrial applications like short-range LiDAR, machine vision and robotics. The 550 aperture PowerBoost VCSEL was selected as a finalist for the Prism Award for Photonics Innovation in the category of vision technology.
