Abstract
An optical device and a light-source device. The optical device includes a first substrate having a first plane and elements, and a second substrate having a second face that faces the first plane. The elements are disposed on the first substrate to emit or receive light in a direction intersecting with the first plane. The second substrate includes lenses disposed to correspond to the elements, and the second substrate extends in a first direction parallel to the second face to contact the first plane. The second substrate has a joint used to determine spacing between the first substrate and the second substrate, and the joint contacts the first substrate with an area smaller than a maximum size of cross-sectional area parallel to the second face of the joint. The light-source device includes the optical device and a driver to drive the optical device.
