Nano-optics: Getting the most out of tiny lasers

8 julio 2014

Semiconductor optical devices are becoming increasingly commonplace. For example, light-emitting diodes, as they become more power efficient, are rapidly replacing conventional light bulbs. Lasers too are now found in every barcode scanner and compact-disc reader. An off-center waveguide enables light to be efficiently extracted from nanoscale lasers.
