Abstract: This application relates generally to an optical fiber for the delivery of infrared light where the polarization state of the light entering the fiber is preserved upon exiting the fiber and the related methods for making thereof. The optical fiber has a wavelength between about 0.9 ?m and 15 ?m, comprises at least one infrared-transmitting glass, and has a polarization-maintaining (PM) transverse cross-sectional structure. The infrared-transmitting, polarization-maintaining (IR-PM) optical fiber has a birefringence greater than 10?5 and has applications in dual-use technologies including laser power delivery, sensing and imaging.

Abstract: A through connector device is disclosed. The device may include a coaxial cable receiver portion defined by one or more surfaces, the coaxial cable receiver portion configured to couple to a center conductor portion of a coaxial cable, the center conductor portion of the coaxial cable protruding above a dielectric material of the coaxial cable. The device may include a beam lead positioned adjacent to the coaxial cable receiver portion. The device may include a planar transmission line contact pad configured to make electrical contact with a planar transmission line of a printed circuit board. The device may include a step configured to electrically and mechanically couple the beam lead to the planar transmission line contact pad, the step configured to create a gap between a bottom surface of the beam lead and a top surface of an outer conductor portion of the coaxial cable.
