| 摘要 |
A layered waveguide stack radiant energy transducer array assembly having a plurality of superposed waveguides, each waveguide having a core layer having a radiant energy transducer disposed therein, and two cladding layers disposed on opposing sides of the core. Each waveguide has at least one inlet for passage of radiant energy therethrough, the inlet extending between the cladding layers, such that radiant energy entering the waveguide impinges on at least two layers of the waveguide. This arrangement provides for 'edge-fed' waveguide, where the energy enters the waveguide from the side, rather than from the top. In some embodiments such as solar panels, energy is harvested. In other embodiments energy is detected such as for example is done in a camera focal plane sensor. In some embodiments the stack is used to emit light. |
