Photonic lanterns
Multimode optical fibers have been primarily (and almost solely) used as “light pipes” in short distance telecommunications and in remote and astronomical spectroscopy. The modal properties of the multimode waveguides are rarely exploited and mostly …
Optical vortices in fiber
Optical vortex beams, possessing spatial polarization or phase singularities, have intriguing properties such as the ability to yield super-resolved spots under focussing, and the ability to carry orbital angular momentum that can impart torque to objects. In …
Nanophotonics of optical fibers
This review is concerned with nanoscale effects in highly transparent dielectric photonic structures fabricated from optical fibers. In contrast to those in plasmonics, these structures do not contain metal particles, wires, or films with nanoscale …
Editorial
Near the beginning of 2013, we were asked by Federico Capasso and Dennis Couwenberg to strategize as to what would make for an interesting and compelling Special Issue on Fiber Optic Technology, especially within the framework of the Journal on Nanophotonics. …
