Ultrafast all-optical differentiators for generation of orthogonal (sub-) picosecond Hermite-Gaussian waveforms

摘要

A novel reconfigurable technique for higher-order temporal differentiation of ultrafast optical waveforms is proposed. Using this method, we experimentally demonstrate efficient generation of temporally orthogonal second and third-order Hermite-Gaussian waveforms in the (sub-)picosecond regime.
