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…
