  • Patent number: 6493072
    Abstract: A system and method for finding the position of a waveguide in a planar optical device that has application to the coupling of light to a planar optical waveguide without connectors. The system comprises input and output optical fiber probes, a light source, a photo or light detector and a optical power meter. The light detector is positioned at the exit of the optical waveguide of interest. Typically, the position of the waveguide will be known with some window of uncertainty. Assuming that the photo detector is a photodiode, the area of the photodiode is preferably large enough that the exit of the waveguide can be assumed to lie within the detection area of the photodiode. The input optical fiber probe is coupled to the light source and is moved across the uncertainty window of the entry to the waveguide. The light transmitted through the waveguide to the photo detector is measured and used to find the position of the entry to the way guide.
