A multi‐field coupling structure is designed and investigated, which combines GaN‐based optoelectronic devices and Terfenol‐D. The abundant coupling effects and multifunctionalities among magnetics, mechanics, electrics, and optics are investigated by a combination of non‐magnetic GaN‐based piezoelectronic optoelectronic characteristics and the giant magnetomechanical properties of Terfenol‐D. A few potential new areas of studies are proposed.
