Abstract
Conference Title: 2015 Conference on Lasers and Electro-Optics (CLEO) Conference Start Date: 2015, May 10 Conference End Date: 2015, May 15 Conference Location: San Jose, CA, USA We investigate the femtosecond dynamics of the spaser emission by combining ab-initio simulations and thermodynamic analysis. Interestingly, the emission is characterized by rotational evolution, opening to the generation of unidirectional emission from perfectly spherical nanoparticles.
