Electrospun fiber mats are currently gaining attention as advanced drug delivery systems. Dissolution testing for such systems is generally performed in small vials by immersing the fiber mats in buffered solutions. Defined aliquots of dissolution medium are withdrawn at predefined time points, and the dissolved drug is quantified. However, this procedure is associated with several drawbacks. T...

Next generation wireless networks must provide high broadband access, which can be achieved by combining the fiber optics and wireless technologies. In this paper we analyze a mm-wave radio over fiber (RoF) optical access network architecture, combining radio subcarrier multiplexing techniques to improve system efficiency with fiber dispersion mitigation provided by optical single sideband modu...

We present a detailed description of the methods used in our model of mode instability in high-power, rare earth-doped, large-mode-area fiber amplifiers. Our model assumes steady-periodic behavior, so it is appropriate to operation after turn on transients have dissipated. It can be adapted to transient cases as well. We describe our algorithm, which includes propagation of the signal field by ...

A new probabilistic shaping distribution that outperforms Maxwell-Boltzmann is studied for the nonlinear fiber channel. Additional gains of 0.1 bit/symbol MI or 0.2 dB SNR for both DP-256QAM and DP-1024QAM are reported after 200 km nonlinear fiber transmission. OCIS codes: (060.0060) Fiber optics and optical communications; (060.1660) Coherent communications.

Group-velocity dispersion of birefringent GeAsSe tapered PCF is directly measured over 1900-2300nm range using all-fiber Mach-Zehnder interferometer. We experimentally prove that zero-dispersion wavelength of chalcogenide PCFs can be shifted to thulium/holmium doped silica emission band.

We demonstrate two-mode multiplexing at 2×10.7 Gbps over 7-cell hollow-core photonic band gap fiber. BER performances below FEC threshold limit (3.3×10 -3 ) are shown for both data channels. OCIS codes: (060.2270) Fiber characterization; (060.2330) Fiber optics communications

We demonstrate a transmission of 8×256 Gb/s WDM 64 Gbaud QPSK signals over 2880 km of standard single mode fiber (SSMF) with erbium doped fiber amplifier (EDFA)-only amplification and coherent detection. OCIS codes: (060.1660) Coherent communications; (060.2330) Fiber optics communications; (060.4080) Modulation.

The current and future growth in telecommunications (National Information Infrastructure) requires technical expertise at all levels to develop, install and operate the equipment. From discussions with the telecommunications industrial leaders, telecommunications and networking professionals are needed. To meet this need, the Electrical Engineering Technology (EET) department at Purdue Universi...

We review our recent progress in the characterization of the embedding of rare-earth elements in nanometer-scale particles or phase-separated glassy regions within the core of silicabased optical fibres, and discuss future directions.
