Light extraction of oblique emissions via collecting the local quasi-mode evanescent wave at the subwavelength scale

原始摘要(英文原文)· Original abstract
Abstract Oblique light emissions are reflected from the interface owing to the total internal reflection. It is found that a waveguide can be used to effectively collect the oblique light emissions of aligned organic dipoles because of the formation of a local quasi-mode evanescent wave. The numerical results show that the highest coupling efficiency and 3 dB spatial deviation of transverse magnetic (transverse electric) wave are 74.3% (78.9%) and 4.1 μ m (5.2 μ m), respectively. The proposed structure can be used in an organic light-emitting device for the applications of silicon photonic integrated circuits.
