We report fabrication of the first low-loss, broadband 37-cell photonic bandgap fiber.Exploiting absence of surface modes and low cross-talk in the fiber we demonstrate mode division multiplexing over...
Air-core photonic bandgap fibers (PBFs) have great potential for the resonant fiber-optic gyroscope (RFOG), because they reduce both the Kerr-induced drift and the thermal polarization ins...
A compact fiber polarizer is demonstrated by the filling of selected air holes of a hollow-core photonic crystal fiber (PCF) with a liquid. The liquid-filling results in an asymmetric waveguide struct...
A novel polarizer is designed by liquidfi lling in partial air-holes of a hollow-core photonic bandgap fi ber(PBGF) forming an asymmetric waveguide structur e, which leads to the vertical polarization...
We report a novel approach for creating a dopant-free pure silica-core waveguide(PSCW) for chip-scale waveguides with the goal of reaching fiber-like losses on-chip.Stoichiometric silica films were us...
Trench-assisted multi-core fiber (TA-MCF) is proposed to achieve high dense MCF design with a solid structure. The crosstalk value at 1.55 μm of fabricated TA-MCF is estimated to be –35 dB at 100 km.
Propagation characteristics of seven-core fiber were investigated for multiplexed signals of spatial-division and wavelength-division. Effect of chromatic dispersion and inter-core crosstalk were eval...
We demonstrate a proof of concept real time HD video stream delivery over 50m 1mm core diameter plastic optical fiber and 3m wireless link employing MB-OFDM UWB technology for in-home networks.
We review the recent progress on hollow-core photonic crystal fibers and its integrated form of photonic microcells in both their design and fabrication and in their applications for coherent optics, ...
Increasing input chirp decelerates (accelerates) the spectral recoiling process across a negative dispersion slope for pulses experiencing normal (anomalous) dispersion. A realistic defect-core photon...
On-chip analog signal performance of high-contrast-grating hollow-core-waveguide is evaluated. SFDR of >100 dB can be achieved for IM3 over a wide RF frequency range of 80 GHz and optical wavelength b...
We experimentally demonstrate 7dB improvement in Brillouin suppression in a photonic crystal fiber by periodically varying the size of the air-hole-structure by only 7% amplitude while keeping a low a...
In this paper, we modeled a core/shell/shell structure with cylindrical Schrodinger-Poisson coupled equation when a magnetic field is (and is not) applied along its axis. We showed the electron densit...
A novel lateral force sensor based on a core-offset tilted fi ber Bragg grating (TFBG) is propo sed and experimentall y demonstrated. The lateral force is determined by the differential refl ected pow...
Power-conversion efficiency reduction on a quasi-homogeneous solid multi-core fiber is numerically investigated. The fiber length dependence of measured crosstalk of fabricated fibers is in good agree...
