The photonic perspective of organic light‐emitting transistors

This article will give an overview of the current state‐of‐the‐art of OLETs from the point of view of their photonic characteristics. In particular, the different device structures realized, the materials used and the strategies implemented to integrate optical resonators and waveguiding structures into light‐emitting field‐effect transistors will be reviewed and the main findings discussed.
