Abstract
A broadcast optical communication system is disclosed. It comprises an optical waveguide having a plurality of gratings. A first grating is disposed at a first node and couples light impinging normally into the waveguide, propagates coupled light bi-directionally through the waveguide and emits a portion of the coupled light at a second grating in a direction normal thereto. An optical source is disposed proximate the first node for transmitting light normally to the first grating and an optical detector is disposed proximate the second node for detecting the normally emitted light. In another embodiment multiple optical waveguides and source-detector pairs are employed in a parallel data architecture to provide multiple channel broadcast communication.
