The new grating was installed in 2012 December ... the polarizer is probably due to room/detector temperature differences because the two measurements were taken on different days. Since the ...

Circular polarization occurs when light waves have ... The nanostructure can then function as efficient emitters, routers, or grating couplers of circularly polarized waves, among other things.
