Advanced optical limiting function based on effective understanding of physical phenomena

摘要

Attention will be paid to cooperative use of linear and nonlinear effects in optical signal processing. This talk reports opportunities and significances of understanding of physical phenomena in order to make further advances in cooperative use of linear and nonlinear effects. In this paper, we focus on optical limiting function using self-phase modulation phenomenon and examine carefully its behaviour assisted by time-resolved spectroscopic technology. Based on the results examined, we successfully achieved high-stable optical limiting function. This optical limiting function achieved wavelength conversion based on self-frequency shift phenomena with preventing influences of input intensity fluctuation.
