Abstract
An optical device and method providing multi-channel bulk optical power monitoring is disclosed. The device and method may include a scanning mirror, a plurality of input optical fibers, a plurality of output optical fibers, and at least one sample optical fiber optically connected to a photodetector. The device and method may further include a first reflective surface and a second reflective surface. The first reflective surface may reflect light from the input optical fibers to the second reflective surface. The second reflective surface may reflect a first portion of the light into the output optical fibers and pass a second portion of the light to the scanning mirror. The scanning mirror may reflect samples of the second portion of the light into the at least one sample optical fiber.
