Latest Patents
One of his latest patents is for a laser diode and method of manufacturing the same. This innovative laser diode is capable of independently driving each ridge section while inhibiting the rotation of a polarization angle that results from stress applied to the ridge section. This design maintains reliability and enhances performance. The laser diode features three or more strip-like ridge sections arranged in parallel, with a strip-like trench in between. It includes a lower cladding layer, an active layer, and an upper cladding layer in that order. Additionally, it has an upper electrode on the top face of each ridge section, which is electrically connected to the upper cladding layer. A wiring layer is also present, electrically connected to the upper electrode and positioned in the air over the trench. Furthermore, a pad electrode is located in a different region from both the ridge section and the trench, ensuring electrical connectivity through the wiring layer.
Another notable patent involves a laser diode that consists of multiple strip-shaped laser structures arranged in parallel. This design includes a lower cladding layer, an active layer, and an upper cladding layer. Each laser structure has a strip-shaped upper electrode that is electrically connected to the upper cladding layer. The wiring layers are also included, ensuring electrical connections to the respective upper electrodes. The design emphasizes the importance of having the wiring layers end in a region separate from where they contact the upper electrode.
