Abstract
For an optical monitor device that detects the intensity of light propagating through an optical fiber, a reduction in size and cost of the optical monitor device are to be achieved.The present disclosure provides an optical monitor device including: an optical component that branches an incoming light at a specific branching ratio and outputs the majority thereof in a specific direction and the rest thereof in another specific direction; a plurality of incoming-side optical fibers through which light is to propagate and that are two-dimensionally arranged to cause the light to enter the optical component; a plurality of outgoing-side optical fibers through which light is to propagate and that are arranged to receive the most outgoing light from the optical component; a light-receiving element located to receive a partial outgoing light from the optical component; an incoming-side lens located between the optical component and the incoming-side optical fibers and that causes the incoming light into the optical component to be a parallel light; and an outgoing-side lens located between the optical component and the outgoing-side optical fibers and that efficiently couples the outgoi…
