Abstract
Ultrafast bandgap photonics in mid-infrared is an exciting area of nonlinear photonics, which shows different ultrafast damage characteristics of solids compared to that in near-infrared fields. It allows periodic surface nano-structures formation in low bandgap materials like germanium. Ultrafast mid-infrared field interaction at 2 micron wavelength with non-linear photonic crystal results in generation of high efficiency harmonic generation up to sixth harmonic.
