Surface emitting device and method for fabricating the same

A method for fabricating a surface emitting device, the method comprising:

• forming a first dielectric layer on a substrate;
• forming a second dielectric layer on the first dielectric layer;
• patterning the second dielectric layer forming a patterned photonic crystal structure;
• coating a polymer electrolyte on the patterned photonic crystal structure forming a polymer electrolyte layer;
• and
• coating a light-emitting material on the polymer electrolyte layer forming a light-emitting material layer.

An optoelectronic device comprising an external resonator consisting of a pair of mirrors and a surface emitting device disposed within the external resonator,

• wherein the surface emitting device comprises;
• a two-dimensional slab type photonic crystal structure including a first dielectric layer and a second dielectric layer formed on top of the first dielectric layer, wherein a plurality of air holes in a two-dimensional lattice pattern are formed on a surface of the second dielectric layer;
• a light-emitting material layer formed on an inner wall defining the air holes;
• and
• optical pumping means for irradiating a lateral surface of the photonic crystal structure with light.
