Document Type and Number:
WIPO Patent Application WO/2022/118861
Kind Code:
A1
Abstract:
Provided is an optical device that enables high-accuracy aligning without causing an increase in manufacturing cost and a reduction in radiation characteristic. This optical device comprises: a substrate; a first sub-substrate that has a first mounting surface and a second mounting surface connected to the first mounting surface via a first step, and is mounted on the substrate; a first light emitting element that is mounted on the first mounting surface, and emits first light having a first wavelength; and an optical element that is mounted on the second mounting surface.
