Concentrated Solar Photovoltaics provide both electricity and heat.
Last pic has a split hybrid CSP system, with visible spectrum PV with an IR reflector, feeding IR to a fiber line for use elsewhere in a high temp electrolysis cell.

OSA | Monolithic ultra-high-Q lithium niobate microring resonator
so lithium niobate makes for great resonators for fiber optic networks, but is chemically inert so you can't etch it easily. Now, it looks like they've achieved usable dry plasma etching to make waveguides/resonators.

Industry sees new opportunities for space manufacturing - SpaceNews.com
ZBLAN fiber optic manufacturing demos on ISS shortly. This is big, because at current ZBLAN pricing, if the orbital manufacturing is viable, it can justify a Bigelow 330 space station and 6 flights a year of SpaceX Dragon to ferry ingots up and fiber down, as a real closing business case.

Icon Polymer
Interesting new hose for probe&drogue aerial refueling systems, which allows power and data transfer at the drogue end unit via a clamping device, as well as telemetry of the end unit, which would be helpful for positioning. An interesting possibility is data transfer from surveillance as their current data collection is starting to exceed reasonable radio transmission capabilities. So, instead of waiting until a UAV returns to the ground to offload data, a UAV could offload data to a command tanker aircraft in theater.

Create the Future Design Contest :: InvisiTower
Interesting take on the tethered electric surveillance quadcopter UAV, using the fiber optic cable tether for data and power. So it isn't spewing surveillance data over RF. Goes up against IAI's ETOP tethered quadcopter though.

Breakthrough MicroSight Technology Improves Iron Sights « Daily Bulletin
This seems to have applications where one of the two things you want to see in focus is a relatively known distance from the lens/eye (in this case the forward blade of an iron sight). I wonder if this has any applications for conventional cameras as a simultaneous multifocal lens?
