Abstract: Vertical cavity surface emitting lasers (VCSELs) and methods of making the same are described. The VCSELs include reliability-enhancing layers that perform specific functions at one or more critical locations within a VCSEL structure to reduce or prevent defect formation and migration that otherwise might degrade VCSEL performance, for example, by increasing optical absorption in the mirror stacks or by degrading the electro-optic properties of the active region. In particular, the reliability-enhancing layers are configured to perform one or more of the following functions within the VCSEL structure: gettering (i.e., removing defects or impurities from critical regions), strain balancing (i.e., compensating the lattice mismatch in the structure to minimize strain), and defect suppression (i.e., creating alloys that reduce the formation of defects during growth or post-growth activities).

Abstract: A vertical cavity surface emitting laser (VCSEL) module that is configured to operate in a wide temperature range without severely minimizing its lifetime or requiring excessive drive current. The VCSEL portion of the VCSEL module is tuned to operate efficiently at a higher than normal temperature. In addition to the VCSEL, the VCSEL module includes a heater and a temperature sensor that are used to maintain a particular minimum temperature that is within the efficient operation range of the VCSEL. By maintaining a temperature that is within the efficient operation range, the VCSEL module reduces the current required to operate the VCSEL and extends the overall lifetime of the VCSEL. The additional components of the VCSEL module do not interfere in any way with the signal quality produced by the VCSEL.

Abstract: A distributed feedback (“DFB”) laser featuring improved manufacturing yield and operational characteristics is disclosed. The present DFB laser includes a bottom confinement layer, an active region, and a top confinement layer disposed atop an n-doped substrate. A p-doped first top layer having a first index of refraction is disposed atop the top confinement layer. A grating is defined in the top surface of the first top layer, and a p-doped second top layer is overlaid on the grating. The two laser end facets are antireflectively coated. The grating is anisotropically etched to define a low kappa grating half and a high kappa grating half. Light waves produced in the active region interact with the grating and are biased toward the low kappa grating half that results in the majority of light signals passing through the end facet adjacent the low kappa grating half.

Abstract: This disclosure concerns distributed feedback (“DFB”) lasers. In one example, a DFB laser includes a body that has first and second end facets. The DFB laser is implemented in a stack configuration that includes an active region interposed between a first top layer and a substrate. A second top layer is disposed on the first top layer and has an index of refraction different from that of the first top layer. Additionally, a grating is defined in one of the top layers and extends from the first end facet to the second end facet. The grating includes a tooth/gap structure whose configuration varies between the first end facet and the second end facet. Finally, an antireflective (AR) coating is disposed on the first end facet and on the second end facet.
