摘要： A feeding fiber cable collectively extracts laser light generated by each of a plurality of fiber laser engines. A processing head converges and emits laser light to a workpiece. A process fiber cable transmits the laser light extracted by the feeding fiber cable to the processing head. The core diameter of the feeding fiber cable and that of the process fiber cable are equal and 50 μm. The plurality of fiber laser engines each have a filter that reduces a value of Raman scattered light in the laser light.

摘要： Back scattering in an optical waveguide at an operating wavelength is controlled by adjusting an optical phase of light propagating in the waveguide at one or more locations along the waveguide. A portion of the back scattered light is tapped off near an input port and coupled into a photodetector. A controller detects changes in the photodetector signal and adjusts an optical phase tuner configured to control the optical phase of light in the waveguide at the selected location or locations. The optical phase tuner may be configured to vary the refractive index of at least a portion of the waveguide.

摘要： An optical assembly includes a combination of laser sources emitting radiation, focused by a combination of lenses into optical waveguides. The optical waveguide and the laser source are permanently attached to a common carrier, while at least one of the lenses is attached to a holder that is an integral part of the carrier, but is free to move initially. Micromechanical techniques are used to adjust the position of the lens and holder, and then fix the holder it into place permanently using integrated heaters with solder.

摘要： An optical package for providing efficient coupling between a photonic device and a silicon photonic integrated-circuit chip (Si PIC) edge couplers with low return loss, as well as variations thereof, is described. The optical package may include a photonic device, a Si PIC, a single mode fiber or fiber array assembly, a lens and a spacer. The Si PIC may an input edge coupler and an output edge coupler. The single mode fiber or fiber array assembly may be aligned to the output edge coupler. The lens may be disposed between the photonic device and the input edge coupler, and may be configured to minimize a mismatch between an output spot size of the photonic device and a spot size of the input edge coupler of the Si PIC. The spacer may be bonded to a facet of the input edge coupler with an index matching fluid.
