Tailoring optical nonlinearities via the Purcell effect
Peter Bermel, Alejandro Rodriguez, John D. Joannopoulos +1
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 o…
Chi2 and chi3 harmonic generation at a critical power in inhomogeneous doubly resonant cavities
Alejandro Rodriguez, Marin Soljacic, John D. Joannopoulos +1
We derive general conditions for 100 percent frequency conversion in any doubly resonant nonlinear cavity, for both second- and third-harmonic generation via chi2 and chi3 nonlinea…
Virtual photons in imaginary time: Computing exact Casimir forces via standard numerical-electromagnetism techniques
Alejandro Rodriguez, Mihai Ibanescu, Davide Iannuzzi +2
We describe a numerical method to compute Casimir forces in arbitrary geometries, for arbitrary dielectric and metallic materials, with arbitrary accuracy (given sufficient computa…
Computation and visualization of Casimir forces in arbitrary geometries: non-monotonic lateral forces and failure of proximity-force approximations
Alejandro Rodriguez, Mihai Ibanescu, Davide Iannuzzi +3
We present a method of computing Casimir forces for arbitrary geometries, with any desired accuracy, that can directly exploit the efficiency of standard numerical-electromagnetism…
