Title:
OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2022/254857
Kind Code:
A1
Abstract:
This optical module comprises a base part and a filter. A first main surface includes a first region and a second region. A first light, a second light, and a third light are multiplexed into a first multiplexed light in the first region. The directions of linearly polarized light of the first light and the second light included in the first multiplexed light are orthogonal. A fourth light and a fifth light are multiplexed into a second multiplexed light in the second region. The filter multiplexes the first multiplexed light and the second multiplexed light into a third multiplexed light by reflecting the first multiplexed light and transmitting the second multiplexed light, or by transmitting the first multiplexed light and reflecting the second multiplexed light. The directions of the linearly polarized light of the third light and the fourth light included in the third multiplexed light are orthogonal.
