Latest Patents

Among his latest innovations is the integrated semiconductor laser apparatus. This apparatus is designed with a core layer positioned near an active layer, allowing it to be in the evanescent-field area of light propagation. The unique arrangement ensures that the carrier concentration of the second cladding layer is higher than that of the first cladding layer. As a result, most evanescent waves of light in the core layer propagate within the first cladding layer, which has a low carrier concentration. This design minimizes the absorption of evanescent waves by carriers, enabling the integrated semiconductor laser apparatus to propagate light with minimal losses. Another notable patent is the distributed feedback semiconductor laser, which further enhances the efficiency and performance of laser systems.
