Abstract: An optoelectronic device providing improved light management is provided. The optoelectronic device includes a substrate having a substantially flat surface, a light management layer provided on the flat surface, such that the light management layer includes a first light management texture. The optoelectronic device also includes a planarization layer on the first light management texture. The planarization layer has a top surface that is defined by a first portion and a second portion, such that the first portion is a substantially flat surface and the second portion includes a second light management texture corresponding to the first light management texture. Further, the second light management texture has dimensions relatively less than that of the first light management texture and the first light management texture and the second light management texture enable light management in a waveguide mode and a surface plasmon polariton (SPP) mode respectively.
