Wavelength-tunable excited-state absorption and optical limiting effects in the Q band region based on silicon phthalocyanine oligomers

摘要

Optical limiting effects of silicon phthalocyanine (SiPc) oligomers have been examined in the Q band region in order to demonstrate a novel concept for controlling the wavelength of optical limiting effects.In nonlinear optical effects, optical limiting effects have attracted considerable attention because of recent developments in optical technology.
