In this work, we investigate the optical properties of solution-processable organic semiconductors that are widely employed in the field of large-area, flexible and portable electronics. The refractive index and extinction coefficient of an n-type organic semiconductor (P(NDI2OD-T2)) were measured in the visible and near infrared range by means of spectroscopic ellipsometry. We also demonstrated integration of P(NDI2OD-T2) as a coating film of low-loss silicon oxynitride waveguides (SiON). Results suggest the possibility to integrate solution-processable electronic devices on photonic integrated circuits and to realize organic transistors on photonic platforms.

Abstract
In this work, we investigate the optical properties of solution-processable organic semiconductors that are widely employed in the field of large-area, flexible and portable electronics. The refractive index and extinction coefficient of an n-type organic semiconductor (P(NDI2OD-T2)) were measured in the visible and near infrared range by means of spectroscopic ellipsometry. We also demonstrated integration of P(NDI2OD-T2) as a coating film of low-loss silicon oxynitride waveguides (SiON). Results suggest the possibility to integrate solution-processable electronic devices on photonic integrated circuits and to realize organic transistors on photonic platforms.File | Dimensione | Formato | |
