Transmission properties of ultrashort pulses propagating through one-dimensional photonic crystals with multiple defects cavities were experimentally investigated. Coupling between multiple cavities is responsible for a wide resonance inside the photonic crystal gap suitable to distortion free propagation of 70 fs pulses at 800 nm. Geometry-induced anomalous dispersion across the resonance allows a compensation of 15% chirp preinduced on Fourier transform limited 70 fs pulses.

Abstract
Transmission properties of ultrashort pulses propagating through one-dimensional photonic crystals with multiple defects cavities were experimentally investigated. Coupling between multiple cavities is responsible for a wide resonance inside the photonic crystal gap suitable to distortion free propagation of 70 fs pulses at 800 nm. Geometry-induced anomalous dispersion across the resonance allows a compensation of 15% chirp preinduced on Fourier transform limited 70 fs pulses.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
