Ultrafast Reflection Control based on Photoinduced Complex Refractive Index Changes in Guided Mode Thin Films Containing Indium Phthalocyanine

Abstract

Abstract Ultrafast all-optical reflection control was achieved by complex refractive index changes upon photoexcitation of indium phthalocyanine in a guided mode geometry device. It gave a few microseconds response mostly characteristic to the lifetime of the excited triplet state.
