1. A waveguide array apparatus, comprising:
a plurality of planar waveguides, each planar waveguide in the plurality having at least a first end, a second end, a first face, and a second face, the second end opposed to the first end along a length of the planar waveguide, at least the first and the second faces forming an at least partially internally reflective optical path along at least a portion of the length of the planar waveguide, and
for each of at least two planar waveguides in the plurality, a respective diffractive optical element disposed between the first and the second ends at respective positions along at least a portion of the length of the respective planar waveguide to partially reflect a respective portion of a spherical wave front outwardly from the first face of the respective planar waveguide.
