Patent ID: 8822906

Claim:
An optical device providing multi-channel bulk optical power monitoring, comprising: a fiber block securing a plurality of input optical fibers, a plurality of output optical fibers, and one or more sample optical fibers in an arrangement of rows and columns, each of the one or more sample optical fibers connected to a respective photodetector; a prism facing the fiber block, the prism comprising first, second, and third reflective surfaces; and a scanning mirror external to the prism, wherein the first reflective surface reflects light from the input optical fibers to the second reflective surface, the second reflective surface reflects a first portion of the light from each input optical fiber into a respective one of the output optical fibers and passes a second portion of the light from each input optical fiber to the third reflective surface, the third reflective surface reflects the second portion of the light from each input optical fiber to the scanning mirror, and the scanning mirror is configured to oscillate about a rotation axis to sequentially reflect the second portion of the light from each input optical fiber into the one or more sample optical fibers.
