Abstract:
1. An optical module which multiplexes a plurality of optical signals emitted from a plurality of light sources and having different wavelengths and outputs a multiplexed optical signal, the optical module comprising: a first optical component which reflects a first optical signal emitted from a first light source and passes at least a second optical signal emitted from a second light source; a second optical component which reflects the first optical signal emitted from the first light source to make it enter the first optical component; a third optical component which reflects the second optical signal emitted from the second light source; and a fourth optical component which reflects the second optical signal reflected by the third optical component to make it enter the first optical component, wherein the first optical component and the fourth optical component are disposed on the same light path, the first light source and the second light source are disposed back and forth along the light path on both sides of the light path, the second optical component and the third optical component are disposed outside the light path, and an incident angle of the first optical signal to the first optical component is smaller than 45 degrees.
