Professional Experience
Dr. Cai has been focusing on the field of on-chip snapshot spectral camera. He proposed and experimentally demonstrated snapshot spectral camera based on photonic crystal slab array. By exploiting abundant wideband dispersion property of photonic crystal and utilizing sparse optimization algorithm, high precision spectral resolution of 0.8nm and spatial resolution of 44×36 are achieved.
