Abstract :
We investigate the internal physical mechanisms of undulated micro-cavity that controls the emission wavelength in organic light-emitting diodes (OLEDs). Finite-difference-domain method is applied to a previously manufactured OLED design featuring optical structure on a wavy over-coat layer. The emission spectrum of dipole oscillation is calculated with various amplitudes of undulation and emission angles.
