OPTICAL PUMPING LIGHT-EMITTING DEVICE AND PREPARATION METHOD FOR MONOLITHIC INTEGRATED OPTICAL PUMPING LIGHT-EMITTING DEVICE

摘要

Disclosed is an optical pumping light-emitting device, comprising: a transparent substrate for the growth of nitride, a yellow-green-red quantum well structure and a covering layer located above the yellow-green-red quantum well structure, wherein a plurality of unit bodies including but not limited to nitride are arranged at a side of the substrate, the unit bodies have a slanted side face, and the yellow-green-red quantum well structure is located on the top of the unit bodies. Further provided is a preparation method for a monolithic integrated optical pumping light-emitting device. Compared with the prior art, the optical pumping light-emitting device in the present invention can reduce pressure stress, and improve light-emitting efficiency.
