Latest Patents

One of Tien-Chang Lu's latest patents is a photonic crystal surface-emitting laser. This innovative device includes a substrate, an n-type cladding layer, an active layer, a photonic crystal structure, a p-type cladding layer, an n-type semiconductor layer, and a meta-surface structure. The n-type cladding layer is positioned over the substrate, while the active layer is situated above it. The photonic crystal structure is placed over the active layer, followed by the p-type cladding layer. Finally, the n-type semiconductor layer is located above the p-type cladding layer, with the meta-surface structure positioned on the surface of the n-type semiconductor layer, away from the p-type cladding layer.

Another notable patent by Lu is also a photonic crystal surface-emitting laser. This version includes a substrate, an n-type cladding layer, an active layer, an index matching layer, and a photonic crystal structure. The n-type cladding layer is again disposed over the substrate, with the active layer above it. The index matching layer surrounds the active layer and is electrically insulating, ensuring that its effective refractive index closely matches that of the active layer. The photonic crystal structure is then placed over both the active layer and the index matching layer.
