A vertical cavity surface emitting laser array is disclosed which allows
wires for individually driving devices arrayed at a small pitch to be
provided on the laser array with ease and with a high degree of freedom
is provided. The vertical cavity surface emitting laser array includes a
first substrate including a plurality of vertical cavity surface emitting
laser devices each having an active layer disposed between reflection
mirrors constituting a resonator, and a second substrate including wires
for providing electrical contact with the surface emitting laser devices
and having a configuration which permits transmission of light emitted
from the surface emitting laser devices. In the vertical cavity surface
emitting laser array, the second substrate is bonded to the first
substrate on the laser emitting side of the first substrate.
