Addressable laser array device including vertical cavity surface emitting lasers adopting nanostructure reflector disposed at intersections of plural wiring patterns

摘要

Provided are an addressable laser array device and an electronic apparatus including the addressable laser array device. The addressable laser array device includes a plurality of VCSELs, each including a distributed Bragg reflector (DBR), a nanostructure reflector including a plurality of nanostructures having a sub-wavelength dimension, and a gain layer disposed between the DBR and the nanostructure reflector; a plurality of first wiring patterns extending in a first direction and being electrically connected to the plurality of VCSELs, respectively; and a plurality of second wiring patterns extending in a second direction intersecting the first direction and being electrically connected to the plurality of VCSELs, respectively, wherein the plurality of VCSELs are disposed at intersections of the plurality of first wiring patterns and the plurality of second wiring patterns, and the addressable VCSEL array device is configured to selectively drive at least some of the plurality of VCSELs.
