Coherent tunneling by adiabatic passage in an optical waveguide system
S. Longhi, G. Della Valle, M. Ornigotti +1
We report on the first experimental demonstration of light transfer in an engineered triple-well optical waveguide structure which provides a classic analogue of Coherent Tunnellin…

Dispersive properties of quasi-phase-matched optical parametric amplifiers
S. Longhi, M. Marano, P. Laporta
The dispersive properties of non-degenerate optical parametric amplification in quasi-phase-matched (QPM) nonlinear quadratic crystals with an arbitrary grating profile are theoret…

Measurement of Superluminal optical tunneling times in double-barrier photonic bandgaps
S. Longhi, P. Laporta, M. Belmone +1
Tunneling of optical pulses at 1.5 micron wavelength through double-barrier periodic fiber Bragg gratings is experimentally investigated. Tunneling time measurements as a function…
