摘要: A broadband partial reflector is located downstream from an optical combiner device. The partial reflector reflects a portion of the combined light back through the combiner device and back into the respective optical pump sources. There are no fiber gratings or other filters between the sources and the combiner device. Consequently, the sources are locked and/or stabilized according to the acceptance bandpass characteristics of the input ports of the combiner device. Since no gratings or other filters need to be located between the sources and the combiner device, the problem of insertion power loss due to spectral mismatch at the input ports can be avoided. In other words, self-aligned wavelength feedback stabilization is accomplished by reflecting a portion of the combined light signal back through the input ports of the combiner device.

摘要: A semiconductor laser having a single transverse mode operation. Optical power higher than that generated by conventional pump lasers is achieved by widening the gain medium without inducing the second transverse mode. This is accomplished by providing a small refractive index difference between active and blocking regions of the laser. The refractive index difference between the laser active region material and the laser blocking region material at the fundamental frequency is less than about 0.029.

摘要: A diamond body, such as a CVD diamond film, is etched by immersion of the body in a molten or partially molten metal, such as the rare earth metal La or Ce. While the body is being etched, various portions of a major surface of the body can be protected for various time durations by masks against the etching--whereby, after dicing the body, the resulting dies can be used as submounts for lasers with feedback.

摘要: The inventive method of producing a device having non-alloyed ohmic contacts of common composition to both an n-doped and a p-doped region of a semiconductor body comprises deposition of a Ti/Pt layer on the p-doped as well as the n-doped region, followed by rapid thermal processing (RTP). Exemplarily, the device is a semiconductor laser, the n-doped region is InP, the p-doped region is InGaAs or InGaAsP, and RTP involves heating in the range 425.degree.-475.degree. C. for 10-100 seconds. The method comprises fewer processing steps than typical prior art methods, reduces the danger of fabrication error and of wafer breakage and, significantly, results in contacts that can be relatively thermally stable and can have very low specific contact resistance (exemplarily as low as 10.sup.-7 .OMEGA..multidot.cm.sup.2).

摘要: A graphite path is formed along the surface of a diamond plate, preferably a CVD diamond plate, by means of a laser or ion-implantation induced conductivity. The path advantageously can be the surface of a sidewall of a via hole drilled by the laser through the plate or a path running along a side surface of the plate from top to bottom opposed major surfaces of the plate. The graphite path is metallized, as by electroplating or electroless plating. In this way, for example, an electrically conducting connection can be made between a metallized backplane located on the bottom surface of the plate and a wire-bonding pad located on the top surface of the plate.

摘要: Disclosed is a method of making a semiconductor device that exemplarily comprises depositing a Ti/Pt layer onto a AuBe intermediate layer on a p-doped region of a semiconductor body. It also comprises depositing a Ti/Pt layer onto a n-doped region of the semiconductor body, or onto a AuGe intermediate layer on the n-doped region, followed by rapid thermal processing. Exemplarily, the device is a semiconductor laser, the n-doped region is InP, the p-doped region is InGaAs or InGaAsP, and RTP involves heating in the range 425.degree.-500.degree. C. for 10-100 seconds. The method comprises fewer processing steps than typical prior art methods, reduces the danger of fabrication error and of wafer breakage and, significantly, results in contacts that can be relatively thermally stable and can have very low specific contact resistance (exemplarily as low as 10.sup.-7 .OMEGA..multidot.cm.sup.2).
