Light source orientation detector

摘要

Apparatus including: an optical waveguide bundle including a plurality of optical waveguides substantially aligned along a waveguide bundle axis, each optical waveguide having a longitudinal core configured to transmit light; a plurality of the optical waveguides each including a Bragg reflector, the Bragg reflectors configured to couple light incident from a direction substantially transverse to the waveguide bundle axis into the optical waveguides in a propagating mode in the longitudinal cores; and each of a plurality of longitudinal cores being in optical communication with an optical detector configured to detect light transmitted in the longitudinal cores.

1. An apparatus, comprising:
an optical waveguide bundle, including a plurality of optical waveguides spaced apart around and substantially aligned along a waveguide bundle axis, each optical waveguide having a longitudinal core configured to transmit light; wherein two of the optical waveguides each include a Bragg reflector, the Bragg reflectors configured to couple light incident from a direction substantially transverse to the waveguide bundle axis into the optical waveguide in propagating modes; wherein each of the two optical waveguides is in optical communication with an optical detector configured to separately detect light from each of the two waveguides; and wherein the optical waveguides are held in alignment in the optical waveguide bundle by a core interposed between the optical waveguides.
