Latest Patents

One of his latest patents is the "Staggered composition quantum well method and device." This invention involves a light-emitting device that features a staggered composition quantum well (QW) with a step-function-like profile. This design enhances radiative efficiency and optical gain by improving electron-hole wavefunction overlap. The staggered QW consists of adjacent layers with distinctly different compositions, allowing for emissions at various target light regimes.

Another notable patent is related to "Nitride based quantum well light-emitting devices having improved current injection efficiency." This III-nitride based device aims to reduce thermionic carrier escape at high current densities. It includes a quantum well active layer and a pair of multi-layer barrier layers arranged symmetrically around the active layer. The design ensures that both barrier layers have bandgaps greater than that of the active layer, thereby enhancing current injection efficiency.
