The oxide confinement layer is disposed between the tunnel junction and MQLs, and has an electrical current aperture defined therein. The mesa structure defines an optical window through which the VCSEL is configured to emit light. | 2021-06-17 |
20210184433 | Method of Fabricating Laser Devices Having Optical Modes Adjustable - A laser device is fabricated to obtain optical modes adjustable. A first distributed Bragg reflector (DBR), a light-emitting layer, a second DBR, and a third DBR are sequentially grown on a substrate through deposition, sputtering, or epitaxy. The third DBR comprises at least one dielectric layer. An aperture is selectively formed at center of the third DBR through etching. On using, the present invention practices the aperture at the dielectric layer on top of the laser device. The optical modes generated is adjustable by controlling the diameter of the aperture or the number of layers contained in the dielectric layer. The divergence angle is decreased to less than 15 degrees, so that the far-field emission has uniform intensity distribution and the emission distance is increased in optical fiber. Thus, a rational structure design, a simple assembly, and a low-cost high-volume manufacture are obtained for mass production. | 2021-06-17 |
20210184434 | LIGHT-EMITTING DEVICE - A light-emitting device according to an embodiment of the present technology includes a first composition changing layer, an interlayer, and a second composition changing layer. The first composition changing layer has a composition continuously changed at a first change rate from a first position to a second position in a thickness direction of the light-emitting device. The interlayer is formed between the second position and a third position in the thickness direction, the interlayer having a composition identical to a composition of the first composition changing layer at the second position. The second composition changing layer has a composition continuously changed at a second change rate from the third position to a fourth position in the thickness direction, the second composition changing layer having, at the third position, a composition identical to the composition of the interlayer. | 2021-06-17 |
20210184435 | DIFFUSION BLOCKING LAYER FOR A COMPOUND SEMICONDUCTOR STRUCTURE - A method of fabricating a gain medium includes growing a p-type layer doped with zinc on a substrate, growing an undoped layer including one or both of InP or InGaAsP on the p-type layer, growing a region that includes multiple quantum wells (MQWs) on the undoped layer, and growing an n-type layer on the region. The undoped layer has a thickness that is sufficient to prevent Zn diffusion from the p-type layer into the region during subsequent growth or wafer fabrication steps. | 2021-06-17 |
