Claim 8:
9. The article of claim 7, wherein:
the corresponding optical sources comprise multiple light-emitting diodes, multiple semiconductor lasers, or a two-dimensional array of semiconductor lasers positioned on a source substrate, and the grating substrate is attached to the source substrate; or
each optical source is a VCSEL formed on a source substrate, and each VCSEL is configured to emit the corresponding incident optical signal beam through the backside of the source substrate; or
the corresponding optical sources are positioned on a source substrate, the grating substrate and the source substrate being (i) a single substrate on which are integrally formed the optical sources and the diffraction gratings, or (ii) separate and discrete substrates with the grating substrate attached directly or indirectly to the source substrate.
