A few top journals and a few association webpages:
Which of these top optics journals do we have? (ranking #1 Scimago, ranking #2 G.Scholar)
Optica (This journal is 100% Open Access)
Nature Photonics (This journal has some Open Access articles. We do not have a subscription. Also see Nature Physics. We do have a full subscription to Nature. See the high profile Science journals on this guide.)
Associations: Optical Society of America, SPIE, EOS, but also AIP, IOP, APS
OSA.org, spie.org, europeanoptics.org
Also, maybe we should just look at the very latest in Web of Science under Category : Optics. (ArXiv also, but careful -- these are not peer-reviewed yet.) Dimensions is fairly new, and you can sort Optics articles for high Altmetrics scores.
Consider setting up alerts. Also many associations and researchers will tell you about their latest work on social media sites.
