google "direct imaging exoplanet", one of the results:
https://en.wikipedia.org/wiki/List_o...ged_exoplanets might be helpful.
There's also a presentation on SEEDS, the exoplanet survey done with Subaru's coronagraph, here:
http://www.astro.uni-jena.de/~theory...ks/kandori.pdf which contains some names and images (as well as the relevant discovery paper references), but drilling down through wikipedia's "exoplanet" entries until you get the list of surveys is probably your best bet.
Of course if by "
optical" you mean "visible", you'll be disappointed, as nIR reradiation is by far the best signal so far for exoplanets (at least known ones, which are predominantly orbiting stars with "considerably" less IR in their emissions (proportionally) -> easier to pick out). It looks like ZIMPOL on one of the VLT units operates at visible wavelengths but is polarimetry really "direct" imaging? I'd need to read (a lot) more to decide...
