Abstract
Light escaping from an optical path, for example via Raman or Rayleigh scattering, can provide information about how light flows in the path, about the optical path, or about matter disposed in the optical path. The path can be a waveguide, an optical channel, or a fiber that may be attached to or integrated with a substrate, for example in a passive or active planar lightguide/lightwave circuit, photonic integrated circuit, semiconductor laser, or optoelectronic element. The escaped light can be color-shifted with respect to the primary light flowing along the path. The escaped light can leave the path at an angle that facilitates detection. Processing or analyzing the scattered light, for example with support of a computing device, can help evaluate the path and/or assess a light intensity pattern thereof, for example to aid design, engineering, testing, qualification, troubleshooting, inspection, manufacturing, etc.
