Phys. Rev. Lett. 99, 053601 (2007) [4 pages]Tailoring Optical Nonlinearities via the Purcell EffectReceived 25 April 2007; published 3 August 2007 We predict that the effective nonlinear optical susceptibility can be tailored using the Purcell effect. While this is a general physical principle that applies to a wide variety of nonlinearities, we specifically investigate the Kerr nonlinearity. We show theoretically that using the Purcell effect for frequencies close to an atomic resonance can substantially influence the resultant Kerr nonlinearity for light of all (even highly detuned) frequencies. For example, in realistic physical systems, enhancement of the Kerr coefficient by one to two orders of magnitude could be achieved. © 2007 The American Physical Society URL:
