The relative refractive index profile of the coupling fiber includes a core region with a profile and a depressed index cladding region that facilitates low bending loss and high bandwidth. The mode field diameter of the coupling fiber is well-matched to standard single mode transmission fibers and the etendue of the coupling fiber is high enough to couple efficiently to multimode transmission fibers.Type: ApplicationFiled: June 7, 2016Publication date: December 29, 2016Inventors: Scott Robertson Bickham, Dana Craig Bookbinder, Ming-Jun Li, Pushkar Tandon

Publication number: 20160377803Abstract: Systems and method are provided for producing portable, high power, broadband terahertz emitters based on arrayed terahertz photoconductive antennas. After such an arrayed structure is made, the phase of terahertz signals that are produced by each photoconductive antenna can be adjusted, and the terahertz signals can be added such that the signals are added constructively. Terahertz emitters based on terahertz photoconductive antenna arrays are advantageously small in size and scalable, allowing for terahertz power to be increased by adding more photoconductive antenna arrays.Type: ApplicationFiled: June 23, 2016Publication date: December 29, 2016Inventors: Dong Ho Wu, Benjamin Graber
