Title:
OPTICAL WAVEGUIDE PACKAGE, LIGHT-EMITTING DEVICE, AND PROJECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/261232
Kind Code:
A1
Abstract:
This optical waveguide package is provided with a substrate having a first surface, a clad located on the first surface, a core located in the clad, and a lens located in the optical path of light emitted from the core. Light emitted from a first element is incident on a first core from a first end, and emitted from a second end. Light emitted from a second element is incident on a second core from a third end, and emitted from a fourth end. A first distance between the second end and the lens is a distance corresponding to the wavelength of the light from the first element, and a second distance between the fourth end and the lens is a distance corresponding to the wavelength of the light from the second element.
