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.

Analysis of the Micromachining Process of Dielectric and Metallic Substrates Immersed in Water with Femtosecond Pulses
Using femtosecond lasers to carve fine holes in stuff using a cover layer of water being exploded. Could this be used to make unearthly PCHE rigs?

FEMTOprint | 3D printing for glass microdevices
Using a femtosecond laser to etch stuff without a photoresist layer, can also etch stuff inside transparent items. You could make a epic PCHE with this, but it would take forever and cost a fortune...

So etching metal surfaces slightly then squishing them together with a light glue makes for a surprisingly strong metal-on-metal bond

A Moon-Based Telescope - Technology Review
The bit about using reactive ion etching to finalize the lunar regolith concrete mirror shape is interesting, though is that before or after they coat the mirror with sputtered aluminum?

Slivers.pdf (application/pdf Object)
The sliver approach marries the production capabilities of silicon wafer PV production (advanced methods not available to thin film processes) with the material efficiency of thin film PV. Though cutting out and extracting/mounting the completed cells must be a major pain...
