Polarization controlled output of electrohydrodynamic jet printed quantum dot embedded photonic crystals for display applications

We demonstrate a replica molded photonic crystal structure with embedded quantum dots in which electrohydrodynamic jet printing is used to control the position of the quantum dots within the device structure. This results in significantly less waste of the quantum dot material and the targeted placement of the quantum dots minimizes any emission outside of the resonant enhancement field, enabling an 8X output enhancement and highly polarized emission from the photonic crystal structure.
