Abstract. A novel method to characterize the organic composition of aerosol particles has been developed. The method is based on organic vapor interaction with aerosol particles and it has been named an Organic Tandem Differential Mobility Analyzer (OTDMA). The OTDMA method has been tested for inorganic (sodium chloride and ammonium sulfate) and organic (citric acid and adipic acid) particles. Growth curves of the particles have been measured in ethanol vapor and as a comparison in water vapor as a function of saturation ratio. Measurements in water vapor show that sodium chloride and ammonium

The receiver performs clock and data recovery (CDR), phase acquisition and forward-error-correction (FEC).

Abstract:
Future optical communication system will probably be a mixture of wavelength division multiplexing (WDM) and optical time domain multiplexing (OTDM). It was shown recently that AlGaAs used at photon energies below the half-band gap is capable of performing OTDM functions[1]. In an OTDM system, signals are alloted different time slots, while in a WDM system, more than one wavelength are used to carry the signals. Hence there is a need to have wavelength shifting components to route signals. Furthermore, if OTDM and WDM are combined, the wavelength shifting will have to be ultrafast.

Abstract:
In future all-optical networks, it is likely that both WDM and OTDM will be incorporated, and there will be a need for all-optical data format conversion/reconversion between WDM and OTDM [1]. Nonretum-to-zero (NRZ) and retum-to-zero (RZ) formats are mostly used among a variety of data formats. NRZ format has the merit of lower bandwidth requirement and higher timing jitter tolerance than RZ format, while RZ format Is preferred in ultra-fest OTDM networks to make use of bit-interleaving technique.

Optical time-division multiplexing (OTDM) is potentially a useful technique for increasing the bit rate of lightwave systems beyond the bandwidth capabilities of drive electronics. We report here a novel optical multiplexing and demultiplexing scheme using mode-locked extended cavity injection lasers and Ti:LiNbO3 waveguide switch/modulators. An OTDM experiment is described in which two separate lasers are mode-locked and externally modulated at 2 GHz, and then optically multiplexed to a bit rate of 4 Gb/s. The 4Gb/s multiplexed signal is transmitted over 8 km of fiber, demultiplexed with a Ti

Abstract:
There has been much recent interest in the use of semiconductor optical amplifiers (SOAs) as ultrafast (40Gb/s and higher) nonlinear switching elements. In particular, SOAs have been employed as wavelength conversion devices for use in wavelength division multiplexing networks and as optical time division de/multiplexing (OTDM) elements such as that reported by Patrick et. al [1]. Here we demonstrate for the first time we believe, a polarisation switching technique in which a 40Gb/s OTDM signal is optically gated by a 10GHz pulse train, affording high extinction ratio, error free demultiplexin

Abstract:
Recently, we have demonstrated several experimental high speed transmission systems using optical time division multiplexing (OTDM) [1,2]. Unlike conventional high speed systems [3], where the data transmitted is modulated using a 50% duty cycle, these OTDM systems use short optical pulses generated by mode-locked extended-cavity semiconductor lasers [4]. Optimum performance in these OTDM systems [1,2], where up to four separate sources are time multiplexed, is limited by fiber dispersion caused by the wide spectral widths and unmatched wavelengths of the different mode-locked lasers [1,2].
