Abstract:
The development of nanotechnology in photonics offers significant scientific and technological potentials. It fosters the substantial efforts for exploring novel photonic materials, developing easy device fabrication techniques, reducing the size of photonic devices, improving device integration density, and fabricating low-cost nanodevices. Since nanometer-scale photonic wires are highly desirable for applications in high density and miniaturized photonic integrated circuits, so subwavelength-diameter wires were fabricated in silica fiber, bulk glass, compound-glass fiber,etc.Meanwhile, miniaturization of photonic devices is being intensively focused because they drive great developments in the fields of optical communications, biophotonics, engineered structures, and photonic integrations. Poly(trimethylene terephthalate) (PTT) is a relatively novel polymer material whichwas extracted from petroleum or refined from corn. In this talk, good transparency of PTT from visible lights to near-infrared and its application for the first time in nanophotonics will be introduced.Subsequently, flexible and elastic nanowires with diameters down to 60 nm and lengths up to 500 mm, which were drawn by a one-step drawing process from the PTT melt, will be presented followed by a number of devices (nanosplitters, nanocouplers, nanorings, nanoresonators, nanotweezer, nanoscissor, nanoscrewdriver, nanobird’s nest, nanosensor, etc.) and nanophotonic integration, which were assembled by the PTT nanowires.
