A diameter--bandwidth product limitation of isolated-object cloaking
Hila Hashemi, Cheng Wei Qiu, Alexander P. McCauley +2
We show that cloaking of isolated objects is subject to a diameter-bandwidth product limitation: as the size of the object increases, the bandwidth of good (small cross-section) cl…
General scaling limitations of ground-plane and isolated-object cloaks
Hila Hashemi, A. Oskooi, J. D. Joannopoulos +1
We prove that, for arbitrary three-dimensional transformation-based invisibility cloaking of an object above a ground plane or of isolated object, there are practical constraints t…
Degenerate four-wave mixing in triply-resonant Kerr cavities
David Ramirez, Alejandro W. Rodriguez, Hila Hashemi +3
We demonstrate theoretical conditions for highly-efficient degenerate four-wave mixing in triply-resonant nonlinear (Kerr) cavities. We employ a general and accurate temporal coupl…
Delay-bandwidth and delay-loss limitations for cloaking of large objects
Hila Hashemi, Baile Zhang, J. D. Joannopoulos +1
Based on a simple model of ground-plane cloaking, we argue that the diffculty of cloaking is fundamentally limited by delay-loss and delaylbandwidth/size limitations that worsen as…
Nonlinear harmonic generation and devices in doubly-resonant Kerr cavities
Hila Hashemi, Alejandro W. Rodriguez, J. D. Joannopoulos +2
We describea theoretical analysis of the nonlinear dynamics of third-harmonic generation () via Kerr ($\chithree$) nonlinearities in a resonant cavity with resonances at bo…
