The present disclosure provides a semiconductor device package. The semiconductor device package includes a substrate having a first surface and a second surface opposite to the first surface, an optical device disposed on the first surface of the substrate, and an electronic device disposed on the second surface of the substrate. A power of the electronic device is greater than a power of the optical device. A vertical projection of the optical device on the first surface is spaced apart from a vertical projection of the electronic device on the second surface by a distance greater than zero.
