Title:
OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2022/153643
Kind Code:
A1
Abstract:
This optical module comprises a base member including a first surface, a first semiconductor light-emitting device that is mounted on the first surface and that is configured to emit first light having a first wavelength, a first filter that is mounted on the first surface and that includes a first reflective surface for reflecting the first light, a second semiconductor light-emitting device that is mounted on the first surface and that is configured to emit second light having a second wavelength different from the first wavelength, and a second filter that is mounted on the first surface and that includes a second reflective surface for reflecting the second light, the first light reflected by the first reflective surface passing through the second filter, the first light and the second light being multiplexed due to the second reflective surface reflecting the second light, and, in the direction perpendicular to the first surface, the length of the first filter being different from the length of the second filter.
