Abstract: A laser module includes: a first laser element having a first emission port that emits first laser light; and a second laser element having a second emission port that emits second laser light. The first laser element and the second laser element are disposed such that the first laser light and the second laser light overlap each other.

Abstract: A MEMS switch includes a first signal line provided in a first beam, a first GND adjacent to the first signal line, a second signal line provided in a second beam, and a second GND adjacent to the second signal line. A contact terminal is fixed to any one of the first signal line and the second signal line and performs connection between the first signal line and the second signal line according to deformation of the first beam.
