Lumentum Announces Five And Six Junction VCSEL Arrays
Designed for advanced consumer, automotive, and other 3D sensing
Lumentum has announced new high-power and high-efficiency five and six junction VCSEL arrays for advanced consumer, automotive LiDAR, and other 3D sensing applications.
Lumentum's five and six junction VCSEL arrays enable much lower power dissipation, very high slope efficiencies, and optical peak powers compared with existing devices. Optical powers exceeding 2 W per individual VCSEL emitter have resulted in over 800 W of peak power from a compact one square millimeter sized VCSEL array. The peak optical power, low thermal dissipation, and small die size of these new multi-junction VCSELs arrays are important to extending their use to high performance all-solid-state medium and long-range LiDAR.
"Automotive, consumer, and industrial customers increasingly need higher performance VCSEL arrays to drive increased functionality and adoption of LiDAR and 3D sensing enabled products," said André Wong, VP of 3D Sensing Product Line Management. "Our latest multi-junction VCSEL arrays continue our long history of pioneering innovative optical solutions in close collaboration with customers. These new products leverage the well proven high-volume, 6-inch wafer supply that we established more than four years ago."
Lumentum's multi-junction VCSEL arrays emit at 940 nm and 905 nm and are manufactured on the same production lines as current high-volume VCSEL array products serving the consumer electronics market.
Lumentum will be showing its product line of lasers and optics for 3D sensing and LiDAR at the SPIE Photonics West 2021 Digital Forum, March 6-11, 2021, along with giving several technical presentations and participating in industry panel discussions.
