Environ Microbiol Rep. 2009 Aug;1(4):220-7. doi: 10.1111/j.1758-2229.2009.00035.x. Epub 2009 Jun 12.

As key components of the electron transfer (ET) pathways used for dissimilatory reduction of solid iron [Fe(III)] (hydr)oxides, outer membrane multihaem c-type cytochromes MtrC and OmcA of Shewanella oneidensis MR-1 and OmcE and OmcS of Geobacter sulfurreducens mediate ET...

Opt Express. 2014 May 05;22(9):10544-9. doi: 10.1364/OE.22.010544.

We report the first demonstration of an inline few-mode thulium doped fiber amplifier (TDFA) operating at 2μm for mode division multiplexed transmission. Similar gain and noise figure performance for both the LP(01) and LP(11) modes are obtained in a...

Accurate calibration of S(2) and interferometry based multimode fiber characterization techniques.

Optics express

Gray DR, Sandoghchi SR, Wheeler NV, Baddela NK, Jasion GT, Petrovich MN, Poletti F, Richardson DJ.
PMID: 25969094
Opt Express. 2015 Apr 20;23(8):10540-52. doi: 10.1364/OE.23.010540.

We present a novel method to validate the relative amount of power carried by high order modes in a multimode fiber using a Spatial and Spectral (S(2)) imaging technique. The method can be utilized to calibrate the S(2) set-up...

Optical side scattering radiometry for high resolution, wide dynamic range longitudinal assessment of optical fibers.

Sandoghchi SR, Petrovich M, Gray DR, Chen Y, Wheeler NV, Bradley TD, Wong NH, Jasion GT, Hayes J, Fokoua EN, Alonso MB, Mousavi SM, Richardson DJ, Poletti F.
PMID: 26480455
Opt Express. 2015 Oct 19;23(21):27960-74. doi: 10.1364/OE.23.027960.

Current optical reflectometric techniques used to characterize optical fibers have to trade-off longitudinal range with spatial resolution and therefore struggle to provide simultaneously wide dynamic range (>20dB) and high resolution (

Optimisation of amplitude limiters for phase preservation based on the exact solution to degenerate four-wave mixing.

Optics express

Bottrill KR, Hesketh G, Parmigiani F, Richardson DJ, Petropoulos P.
PMID: 26906847
Opt Express. 2016 Feb 08;24(3):2774-87. doi: 10.1364/OE.24.002774.

Adopting an exact solution to four-wave mixing (FWM), wherein harmonic evolution is described by the sum of two Bessel functions, we identify two causes of amplitude to phase noise conversion which impair FWM saturation based amplitude regenerators: self-phase modulation...

The prevalence and significance of precopulatory mate choice remains keenly debated. The major histocompatibility complex (MHC) plays a key role in vertebrate adaptive immunity, and variation at the MHC influences individual survival. Although MHC-dependent mate choice has been documented...

We report a nonlinear signal processing system based on a SiGe waveguide suitable for high spectral efficiency data signals. Four-wave-mixing (FWM)-based wavelength conversion of 10-Gbaud 16-Quadrature amplitude modulated (QAM) and 64-QAM signals is demonstrated with less than -10-dB conversion...
