Non‐Volatile Silicon Photonics Using Nanoscale Flash Memory Technology - Grajower - - Laser & Photonics Reviews - Wiley Online Library
MONOS allows using conventional NAND flash CMOS manufacturing techniques to yield potentially terahertz speed circuits. Heat is probably still a problem, but this may make chip internal optics easier, as well the mentioned filter/switch/modulator/resonater/laser optics applications

Coherent Perfect Absorbers
Interesting research on creating the opposite of a laser, a sort of antilaser. A loss medium basically disrupts a laser, which had been amplified in a gain medium. Demo is near IR. Hoping for slightly more broadband sources. Could be used for laser heat absorbers as a thermal laser receiver in remote power beaming applications...

NREL: News Feature - Breakthrough Furnace Can Cut Solar Costs
Interesting tricks to use the material properties of solar cells to ease the burden of heating them during manufacturing, increasing efficiency and lowering power and cooling requirements. The optical cavity and mirror ceramics are a good fit here, but may not be all that applicable elsewhere though.

[0912.5390] Highly efficient photovoltaic energy conversion using surface acoustic waves in piezoelectric semiconductors
I think this is implying using piezoelectric setup, where an acoustic wave wiggles the material, creating imbalances to collect solar PV charges (rather than inherent doped electrons and holes like normal solar cells), which get hauled over to electrodes. I don't think this is implying something like thermoacoustic piezoelectric generators...

Fundamental Breakthrough Enables Previously Impossible Semiconductors and Nanomaterials to be Created
Ok, they can make spheres of the oddball stuff, but what about sheets? If they can't make sheets (which I would think would be hard when doing solution based nucleation) then the usefulness of this will be for a more niche market, unless you do other composite tricks.
