'Like a field plowed prior to planting': Researchers want to grow lasers, yes lasers, on material commonly found in sand
They begin by covering a silicon wafer with a layer of silicon dioxide and etching in arrowhead-shaped trenches (“like a field plowed prior to planting” as IEEE Spectrum describes it).
