Phys. Rev. Lett. 102, 203903 (2009) [4 pages]Accessible Light Bullets via Synergetic NonlinearitiesReceived 5 February 2009; published 19 May 2009 We introduce a new form of stable spatiotemporal self-trapped optical packets stemming from the interplay of local and nonlocal nonlinearities. Pulsed self-trapped light beams in media with both electronic and molecular nonlinear responses are addressed to prove that spatial and temporal effects can be decoupled, allowing for independent tuning. We numerically demonstrate that (3+1)D light bullets and antibullets, i.e., bright and dark temporal solitons embedded in stable (2+1)D nonlocal spatial solitons, can be generated in reorientational media under experimentally feasible conditions. © 2009 The American Physical Society URL:
