Beating LIDAR - Achuta Kadambi - MIT Media Lab
Using heterodyning LIDAR to achieve very high resolution at range, and might be able to punch through fog. WHich makes you wonder if the same trick could be used for lasercomm lasers which always had a rain/fog fade problem...

Moore’s law really is dead this time | Ars Technica
"But even these new techniques were up against a wall. The photolithography process used to transfer the chip patterns to the silicon wafer has been under considerable pressure: currently, light with a 193 nanometre wavelength is used to create chips with features just 14 nanometres."
