would pic relate but scaled down to nanometer length works on visible light?

in principle yes, but in practice you'll find that constructing an antenna so small and running it at such high frequencies is not practical.

metals are extremely lossy at optical frequencies

no, material properties are different for that frequency range

Small antennas for visible light already exist, they're called fluorescent molecules
FFS people on this board need to learn some science

In don't really think you can get an antenna that small to be like that. Maybe though here is an example if a nano antenna.
