Latest Patents
One of Taike's latest patents is for a distributed feedback semiconductor laser equipment employing a grating. This invention addresses the issue of deteriorating laser characteristics at high temperatures due to high device resistance in prior art distributed feedback lasers with an InGaAlAs active layer. The innovative design involves fabricating a ridge type laser by forming an InGaAlAs-MQW layer on a n-type InP substrate, followed by the growth of a p-type InGaAlAs-GRIN-SCH layer, a p-type InAlAs electron stopping layer, and a p-type grating layer. The grating is formed with a concave depth smaller than the thickness of the p-type grating layer.
Another notable patent is for an optoelectronic waveguiding device and optical modules. This optical transmission device is designed for high-speed and large-capacity optical transmission systems. It includes an optical waveguide layer and cladding layers, each having a larger band gap than that of the optical waveguide. The device features optical waveguides with a MQW structure along the light propagation axis of the optical waveguide layer, allowing for enhanced performance in optical communication.
