    摘要： A method and apparatus for fabricating a metamorphic long-wavelength, high-speed photodiode, wherein a buffer layer matching a substrate lattice constant is formed at normal growth temperatures and a thin grading region which grades past the desired lattice constant is configured at a low temperature. A reverse grade back is performed to match a desired lattice constant. Thereafter, a thick layer is formed thereon, based on the desired lattice constant. Annealing can then occur to isolate dislocated material in a grading layer and a reverse grading layer. Thereon a strained layer superlattice substrate is created upon which a high-speed photodiode can be formed. Implant or diffusion layers grown in dopants can be formed based on materials, such as Be, Mg, C, Te, Si, Se, Zn, or others. A metal layer can be formed over a cap above a P+ region situated directly over an N-active region. The active region also includes a p-doped region. The high-speed photodiode can thus be formed utilizing GaAs, or other substrate material, such as germanium and silicon.

    摘要： Digital electronic devices for optical communication of digital video and/or audio signals between a digital source device and a digital sink device. A digital source device includes a transition minimized differential signaling (TMDS) transmitter for receiving control and digital video signals from a source controller and for converting the control and digital video signals into electric TMDS signals. An interface receives a first end of an optical fiber. An optical transmitter converts the electric TMDS signals to at least one optical signal and transmits the at least one optical signal to the first end of the optical fiber. A digital sink device receives the at least one optical signal from a second end of the optical fiber and converts the optical signal into TMDS signals. A TMDS receiver converts the TMDS signals into control and digital video signals and transmits the control and digital video signals to the sink controller.

    摘要： Multiple laser optical sensing systems and methods for detecting target characteristics are disclosed. The present invention detects the presence of an object in a monitored area using an laser-based object detection system and may selectively cause a controlled response when an object is detected. At least two laser signals may be emitted into a monitored area using a vertical cavity surface emitting laser structure. At least one detector receives any laser signals not blocked by an object. The system determines the presence or absence of an object in the environment using a microprocessor and determines the objects characteristics by comparing received laser signals associated with it to object characteristics stored in a memory. The system may selectively causing a controlled response in accordance with the determination of object characteristics and/or correlating response criteria.

    摘要： A multiple laser optical sensing system and method for detecting target characteristics are disclosed. The system includes a laser source with at least two emission apertures from which laser signals are emitted. The system also includes at least one detector, which is operationally responsive to the laser source. Finally, the system includes a microprocessor that is operationally coupled to the detector(s). In operation, the laser source emits into an environment at least two laser signals, one from each emission aperture. The detector detects the laser signals after the signals pass through the environment, which is occupied by a target and the microprocessor determines target characteristics based on the laser signals received by the detector(s).
