A Fourier beam propagation algorithm for within a lens Rayleigh region is derived within the Talanov framework, accommodating both the large beam size changes and propagation distances typical for large, complex systems as the NIF.
NIF's ability to deliver precise, high-contrast pulses is limited by the fidelity of our numerical model. Model fidelity is enhanced by fitting small-signal gain and saturation parameters to measurements and by including temporal overlap effects.
We have achieved the NIF design goals for power and energy by delivering 1.86 MJ of ultra-violet energy in a wide dynamic range (>300:1), 22.5-ns shaped ignition pulse with a peak power of 520 TW.
The Q-factor of a localized plasmon cavity is enhanced significantly when allowing the plasmon to very slightly propagate as an SPP. The resulting mixed plasmon - plasmon polariton resonators retain sub-100 nm volume with enhanced Q-factors.
Abrupt near IR optical pulses launched over metal-dielectric interface are exhibiting wavefronts moving almost at the speed of light in vacuum (much faster than plasmonic wavepackets) and comprised of much lower frequencies (tens of THz).
Plasmonic wave is perfectly split to 4 identical waves when encountering nano intersection. This is substantially different from photonic waveguides exhibiting negligible coupling to vertical segments. Larger plasmonic junction is exhibiting retardation and memory effects.
The effective index concept validity is studied for plasmonic gap nano-circuitry: waveguides, resonators and self-guiding. Contrary to unique and adverse characteristics of plasmonic modes in nano-devices, the EI analysis fairly agrees with the simulation results.
Self focusing and spectral shaping of single-interface plasmon polariton due to the intrinsic metal plasma nonlinearity is predicted. Initial experimental demonstration of the above phenomena is reported.
A 50 nm diameter gold cylinder loaded on a semiconductor surface creates sub-wavelength field confinement in 3D. The virtual nano-cavity exhibits 180 nm modal volume with Q-factor of few hundreds, suitable for realizing a semiconductor based nano-laser.
Plasmonic circuit elements, which are based on complementary waveguide structures (waveguides with a dielectric core and metal cladding), are becoming preferred plasmonic devices for applications. In this paper, we look into the modeling of such devices, namely 1D waveguides and related elements as well as 2D slots, trenches, and channels supporting plasmonic slow waves. Methods such as the effective...
Formation of novel hybrid vector spatial plasmon-soliton in Kerr slab in-between metal plates is analyzed with a novel NLSE. The soliton self-trapping in lateral dimension is assisted by the plasmonic effect.
Inserting a 2D dielectric photonic band gap cavity structure between nano-spaced plasmonic metal plates enables confinement of light with no apparent lower bound to the modal volume and to radiation losses in the vertical direction
