  • Publication number: 20190196224
    Abstract: A dual defocus lens is disclosed in the present invention. The dual defocus lens comprises a refractive-error correction part, a positioning part and a periphery part. The refractive-error correction part comprises a central optical region, a first defocus region and a second defocus region. The first defocus region, the second defocus region, the positioning part and the periphery part are all concentric to the central optical region having the same center as the refractive-error correction part. The first defocus region and the central optical region have different diopters individually for correcting the positions of imaging on the retina. The second defocus region having small radius of curvature provides shorter focus for imaging in the front of the retina. Thus, the retina will not be elongated or deformed gradually due to the image beyond the retina so that the myopia can be greatly controlled.

  • Patent number: 10122152
    Abstract: A vertical-cavity surface-emitting Laser (VCSEL) has a three-trench structure. By forming a first trench within a mesa around the periphery of an output window of the VCSEL, the overall capacitance is decreased and the time used in the oxidation process for an oxidation layer is shortened. By forming a second trench and a third trench on the periphery of the mesa in a step-like concave manner, the mesa becomes a step-like structure having double mesa-layers. Such that, a larger heat-radiating area can be obtained for decreasing thermal effects, while the metal-gap defects of the metal layer can also be avoided. The implant layer is formed around the periphery of the output window for controlling the optical mode and confining the current path. In addition, an output layer is formed on the output window for controlling the output light.
