摘要： Systems and methods for multiple beam additive manufacturing use multiple beams of light (e.g., laser light) simultaneously to expose layers of powder material in selected regions until the powder material fuses to form voxels, which form build layers of a three-dimensional structure. The light may be generated from selected light sources and coupled into an array of optical fibers having output ends arranged in an optical head such that the multiple beams are directed by the optical head to different locations on each of the powder layers. The multiple beams may provide distributed exposures forming a distributed exposure pattern including beam spots that are spaced sufficiently to separate the fused regions formed by each exposure. The multiple beams may be moved using various techniques (e.g., by moving the optical head) and according to various scan patterns such that a plurality of multiple beam distributed exposures form each build layer.

摘要： Systems and methods for laser drilling provide laser beam energy modification to reduce (e.g., eliminate or minimize) back-wall strikes during laser drilling. The systems and methods modify the process laser beam energy such that a beam energy at a central region of the process laser beam is less than a beam energy at an outer region of the process laser beam. In one example, the modified process beam has zero beam energy at the central region, thereby providing a "donut mode." The laser beam energy modification may be achieved by detuning a fiber coupler in the Z axis such that laser energy is coupled into a cladding layer of the process fiber coupled to the laser fiber via the fiber coupler.

摘要： A tunable laser with multiple in-line sections generally includes a semiconductor laser body with a plurality of in-line laser sections each configured to be driven independently to generate laser light at a wavelength within a different respective wavelength range. The wavelength of the light generated in each of the laser sections may be tuned, in response to a temperature change, to a channel wavelength within the respective wavelength range. The laser light generated in each selected one of the laser sections is emitted from a front facet of the laser body. By selectively generating light in one or more of the laser sections, one or more channel wavelengths may be selected for lasing and transmission. The tunable laser with multiple in-line sections may be used, for example, in a tunable transmitter in an optical networking unit (ONU) in a WDM passive optical network (PON) to select a transmission channel wavelength.

摘要： In a laser package, a tilted laser causes laser light to be coupled into an optical fiber at an angle relative to a fiber axis of the optical fiber. The tilted laser emits laser light at an angle relative to a lens axis of a lens such that the lens directs and focuses the laser light at the angle relative to the fiber axis. Tilting the laser allows the laser light to be coupled into the optical fiber substantially parallel to or aligned with the core of the fiber while causing back reflection to be directed away from the laser, thereby improving coupling efficiency and minimizing feedback. The tilted laser may be coupled to an angle polished fiber, for example, in a laser package such as a TO can type laser package, a butterfly type laser package, or a TOSA type laser package.

摘要： A distortion compensation circuit compensates for distortion generated by one or more non-linear elements such as a laser device. The distortion compensation circuit may be used in an optical transmitter, such as a laser transmitter used for forward path CATV applications. The distortion compensation circuit may include a primary signal path and a secondary signal path that receive an input signal. The secondary signal path produces distortion of a magnitude corresponding to the magnitude of, but at an opposite phase to, the distortion generated by the non-linear amplifier. The secondary signal path includes a plurality of distortion sub-paths with each of the distortion sub-paths configured to produce intermodulation distortion products of the same distortion order but for different frequency dependent orders in a time dependent series representative of the distortion produced by the non-linear amplifier.

摘要： A system for reducing clipping may be used between a multichannel RF source and a laser to reduce or correct clipping that might occur in the laser as a result of negative spikes or peaks in a multichannel RF signal. The system generally includes a clipping correction circuit that receives the multichannel RF signal and responsive to the RF signal, prevents one or more of the negative peaks in the RF signal from causing clipping. The clipping correction circuit may either detect an envelope of the RF signal and/or may detect one or more peaks in the RF signal. One or more negative peaks may be prevented from causing clipping by adjusting a bias current provided by a bias control circuit and/or by modifying the RF signal with one or more clipping correction pulses coinciding with one or more negative peaks.
