• High‐speed electromagnetic characteristics of an organic light‐emitting diode (OLED) are explored in this paper. When a high‐frequency (∼14 GHz) microwave pulse is injected into an OLED, the pulse is split into two peaks: one peak is delayed by 1.725 ns and another one is advanced by 0.183 ns, which also suggests the existence of an extremely low‐speed group velocity. The effective thickness of the OLED sample is ∼355.8 nm and, as a result, the effective index of refraction is ∼107 when the splitting phenomenon occurs. © 2005 Wiley Periodicals, Inc.
