Abstract
In this invited contribution I will review recent results of our research in the field of complex nanolasers. I will begin by discussing recent experimental results from a new type of ultra-dark nanoparticles, which behave as an ideal black-body and spontaneously produce single color pulses thanks to an equivalent Bose-Einstein Condensation of light.(1) I will then discuss new quantum information sources from core-shell spaser nanoparticles.(2) Finally, I will illustrate a new type of laser source that emits only in the near field, discussing applications in integrated optical circuits.
