Subpicosecond-scale change in transmission spectrum of vacuum-deposited thin-film CdS interferometers

摘要

To our knowledge we report the first fabrication of vacuum deposited thin film interferometers with an intermediate layer doped by quantum-confined semiconductor microcrystallites. These filters demonstrate new spectral and optical properties in addition to those typical for samples deposited by conventional thermal evaporation, and, in particular, high-speed optical switching with picosecond on/off time.
