Abstract: A broadband spectral power generator in a multimode optical fiber utilizes a standard multimode fiber that is coiled. A plate is placed on the coiled fiber and a force is applied to compresses the coiled fiber and thereby increase the interactions between the compressed windings and induce modal mixing and birefringence in the fiber. In addition, the compression causes additional non-linear processes to be excited and occur in the compressed fiber coil to generate more broadband light. This allows for better "mixing" of the spatial beam in the multimode fiber coil and allows for the various modes to overlap. The multimode fiber coil is made of silica, silicate, germinate, phosphate, fluoride, chalcogenide, or telluride. The compressed coiled fiber may be driven by a laser providing more than one wavelength output and this greatly increases the amount of nonlinear mixing in the fiber for a greatly enhanced spectral coverage.

Abstract: A method and apparatus for laser beam splitting and shaping is disclosed wherein two beam splitters are used to split one input laser beam into four beams in a generally rectangular pattern. Half-wave plates are used to adjust the power of the input laser beam between the four laser beams. A variable power optical telescope comprising negative and positive lens pairs for the four laser beams is used to adjust the divergence of the four beams, and pointing control prism wedges are used to point or steer the four beams to be parallel to each other and to adjust their relative spacing to create a flat top profile.

Abstract: A low voltage, switch mode PHEMT power amplifier with a 0.1 μm gate length and a low loss, lumped element, output matching circuit is disclosed that provides high performance over a frequency range of 1.4 GHz - 2.5 GHz. The amplifier makes use of monolithic circuit technology for the first stage and output transistor, and uses a printed circuit board with surface mount components for the output matching network. The power output of the power amplifier is stable over a range of 60 degrees centigrade, has high power efficiencies of 44 - 53% with greater than 2 watts output power over the frequency range of 1.4 GHz and 2.5 GHz. In addition, through drain voltage control, the output power can be varied over a wide range between about 0.8 to 2.5 watts while still maintaining a high efficiency in the range of 50 ± 3%.
