Patent abstract
An optical module includes a light source, a variable transmittance member disposed on a light path of output light from the light source distant from the light source, and a coupling section for coupling the output light from the light source via the variable transmittance member, wherein coupling efficiency as a ratio between intensity of the light from the light source and intensity of light to be coupled to the coupling section rises in conjunction with a rise in temperature.
