Light-emitting diode chips with optically pumped quantum well structures

Abstract

Light-emitting diode (LED) devices and more particularly LED chips with optically pumped quantum well structures are disclosed. LED chips include electrically pumped quantum well structures positioned proximate p-n junctions, and optically pumped quantum well structures positioned to receive photons of light generated by the electrically pumped quantum well structures and re-emit light having longer peak wavelengths. Aggregate emissions may include broader emission spectrums. Moreover, aggregate emissions may predominately be provided by light from the electrically pumped quantum well structures while light from the optically pumped quantum well structures may provide wavelengths that appear brighter to the human eye to increase luminous flux. Various LED chip structures are disclosed that provide arrangements for flip-chip structures that position optically pumped quantum well structures in intended light paths while reducing interactions with electrical paths within LED chips
