All-optical TDM data Demultiplexing at 80 Gb/s with significant timing jitter tolerance using a fiber Bragg grating based rectangular pulse switching technology
Journal of Lightwave Technology, 2003Co-Authors: L.k. Oxenlwe, Morten Ibsen, David J. Richardson, A.t. Clausen, K.s. Berg, P. JeppesenAbstract:We demonstrate the use of fiber Bragg grating based pulse-shaping technology to provide timing jitter tolerant data Demultiplexing in an 80 Gb/s all-optical time division multiplexing (OTDM) system. Error-free Demultiplexing operation is achieved with ∼6 ps timing jitter tolerance using superstructured fiber Bragg grating based 1.7 ps soliton to 10 ps rectangular pulse conversion at the switching pulse input to a nonlinear optical loop mirror (NOLM) demultiplexer comprising highly nonlinear dispersion shifted fiber (HNLF). A 2-dB power-penalty improvement is obtained compared to Demultiplexing without the pulse-shaping grating.

Timing Jitter Tolerant All-Optical TDM Demultiplexing Using a Saw-Tooth Pulse Shaper
IEEE Photonics Technology Letters, 2008Co-Authors: Francesca Parmigiani, Trina T. Ng, Peter Petropoulos, Morten Ibsen, David J. RichardsonAbstract:We experimentally demonstrate the generation of picosecond saw-tooth optical pulses, which are shaped using a fiber Bragg grating to provide timing jitter tolerant optical time-division multiplexing data Demultiplexing in a scheme based on cross-phase modulation in an optical fiber, with subsequent offset filtering. A power improvement of more than 5 dB is obtained compared to Demultiplexing with more conventional shapes, such as Gaussian, with a similar pulsewidth.

Signal-to-noise ratio analysis of 100 Gb/s Demultiplexing using nonlinear optical loop mirror
Journal of Lightwave Technology, 1997Co-Authors: K. Uchiyama, S. Kawanishi, T. Morioka, H. Takara, M. SaruwatariAbstract:This paper investigates experimentally and theoretically the signal-to-noise ratio (SNR) characteristics of 100 Gb/s all-optical Demultiplexing using a nonlinear optical loop mirror (NOLM). The analysis takes into account two effects that degrade the SNR associated with NOLM Demultiplexing. First is channel crosstalk originating from the leakage of nontarget channels. Second is the intensity fluctuations of demultiplexed signals caused by the combined effects of timing jitter and a profile of the switching window. Considering these two effects, power penalties associated with NOLM. Demultiplexing are theoretically evaluated using the conventional noise theory of an optical receiver followed by an optical preamplifier. Experimental results of bit error rate measurements for 100 Gb/s Demultiplexing using three different NOLMs with different intrinsic crosstalk values, defined by signal transmittance in the absence of control pulses, show that the power penalties are in good agreement with the evaluation based upon our proposed analysis. It can be found from our investigation in Demultiplexing from 100 to 10 Gb/s that intrinsic crosstalk of less than -25 dB, corresponding to a coupling ratio, K, of |K-0.5|/spl les/0.03, is required for the power penalty of less than 1 dB. The root-mean-square (rms) value of the relative timing jitter necessary for obtaining a sufficient timing tolerance width for combining control and signal pulses is determined.

100 gbit s 200 km optical transmission experiment using extremely low jitter pll timing extraction and all optical Demultiplexing based on polarisation insensitive four wave mixing
Electronics Letters, 1994Co-Authors: S. Kawanishi, H. Takara, T. Morioka, O Kamatani, M. SaruwatariAbstract:Fully time-division-multiplexed 100 Gbit/s optical transmission is successfully demonstrated through a 200 km fibre, followed by PLL timing extraction and 100 to 6.3 Gbit/s all-optical Demultiplexing based on polarisation-insensitive four-wave mixing. The prescaled, 0.3 ps jitter 6.3 GHz clock is recovered from the 100 Gbit/s signal using the four-wave mixing light generated in a polarisation-insensitive 100 GHz laser-diode-amplifier phase detector. Polarisation-insensitive four-wave mixing Demultiplexing is achieved by a polarisation rotating loop mirror configuration. >
