Paper Abstract

Transmission properties of ultra-short pulses propagating through 1-D photonic crystals (PCs) with multiple cavities were experimentally investigated. Coupling between cavities is responsible for a wide resonance, inside the PC gap, suitable to distortion free propagation of 70 fs pulses at 800 nm. Geometry induced anomalous dispersion across the resonance allows chirp compensation of 70 fs pulses. We use an autocorrelator set-up in order to investigate chirp compensation effect by measuring the time duration of input and output pulses. Measurements are performed for different incidence angle. Results show that complete chirp compensation of 10 fs chirping occurs for an incidence angle of 20 deg.
