摘要： Raman amplifier equipment for fiber-optic communications links is provided. Raman pump light at a first wavelength or wavelengths may be used to optically pump fiber in a communications link to produce Raman gain. Raman pump light at a second wavelength or wavelengths may be used to optically pump the fiber to produce Raman gain for channels at different wavelengths in the communications link. The Raman gain produced by the pump light at the first wavelength or wavelengths increases the reach of the Raman pump light at the second wavelength or wavelengths into the fiber to improve the noise figure of the amplifier.

摘要： Optical amplifiers are provided in which optical gain is produced by Raman pumping fiber. The Raman-pumped fiber may be a span of transmission fiber or a coil of fiber in a discrete amplifier. Raman pump light may be provided using laser diodes operating at different wavelengths. The Raman pump light that is produced by the laser diodes may be modulated to reduce pump interactions in the fiber. Raman pump light may be modulated by directly modulating the laser diodes or by using optical components that modulate constant power pump light from the laser diodes.

摘要： Distributed Raman amplifier systems are provided in which gain transients are controlled. Signal taps may be used to monitor optical signal powers at network nodes. A telemetry channel may be used to share information between nodes. Information on the output power of a given node may be passed to a subsequent node using the telemetry channel. The subsequent node may use feed-forward and feedback control schemes to control Raman gain transients in the preceding transmission fiber span based on the output power information received over the telemetry channel.

摘要： Optical amplifiers are provided that have dispersion-compensating fiber that is pumped with an optical source to produce Raman gain. Removable modules of dispersion-compensating fiber, which may be separate from the Raman-pumped dispersion-compensating fiber, may be used to adjust the amount of dispersion compensation provided by a given amplifier. The Raman pump may be formed using fiber-Bragg-grating-stabilized diode lasers or other suitable pump sources. Two cross-polarized diode lasers may be used for the Raman pump to reduce the dependence of the Raman gain on the polarization of the pump. If desired, the dispersion-compensating fiber may be Raman pumped using a two-pass configuration in which pump light reflects off of a reflector to produce additional gain. The reflector may be a Faraday rotator to minimize polarization-dependent pump effects.

摘要： A multivariable solver for proximity correction uses a Jacobian matrix to approximate effects of perturbations of segment locations in successive iterations of a design loop. The problem is formulated as a constrained minimization problem with box, linear equality, and linear inequality constraints. To improve computational efficiency, non-local interactions are ignored, which results in a sparse Jacobian matrix.

摘要： A GaN/AlN superlattice is formed over a GaN/sapphire template structure, serving in part as a strain relief layer for growth of subsequent layers (e.g., deep UV light emitting diodes). The GaN/AlN superlattice mitigates the strain between a GaN/sapphire template and a multiple quantum well heterostructure active region, allowing the use of high Al mole fraction in the active region, and therefore emission in the deep UV wavelengths.
