In this paper, demonstration shows that the optical power level necessary for particle trapping can be achieved by lensed VCSELs. Therefore, the next step will be to adopt lensed VCSELs in integrated optical tweezers. Nowadays, commercial optical tweezers are mainly based on Nd:YAG lasers or edge-emitting laser diodes which are either bulky or need careful external beam correction. Here, the use of...
