There's been some work being done on the visible spectrum for some time, with the usual mixed results. When the USN can "cloak" a carrier ... I'd say the tech is mature. Not there yet, eh?
Manipulation of visual spectrum seems to be like fusion powered reactors:
"We'll have it sorted out in about fifteen years"
being the party line for about fifty years ...
