Abstract
According to one aspect, a waveguide comprises a waveguide body having a coupling cavity defined by a coupling feature disposed within the waveguide body. A plug member comprises a first portion disposed in the coupling cavity and an outer surface substantially conforming to the coupling feature and a second portion extending from the first portion into the coupling cavity. The second portion includes a reflective surface adapted to direct light in the coupling cavity into the waveguide body.
