spin wave Frequency Division Multiplexing in an yttrium iron garnet microstripe magnetized by inhomogeneous field
Applied Physics Letters, 2019Co-Authors: Zhizhi Zhang, Jose Holanda, Benjamin M Jungfleisch, Michael Vogel, J Pearson, Yi Li, Ralu DivanAbstract:Spin waves are promising candidates for information processing and transmission in a broad Frequency range. In the realization of magnonic devices, the Frequency related Division of the spin waves is a critical function for parallel information processing. In this work, we demonstrate a proof-of-concept spin-wave Frequency Division Multiplexing method by magnetizing a homogeneous magnetic microstripe with an inhomogeneous field. The symmetry breaking additional field is introduced by a Permalloy stripe simply placed in lateral proximity to an yttrium iron garnet waveguide. Spin waves with different frequencies can propagate independently, simultaneously, and separately in space along the shared waveguide. This work demonstrates one potential way for parallel information transmission and processing in magnonics.Spin waves are promising candidates for information processing and transmission in a broad Frequency range.

orthogonal Frequency Division Multiplexing for dispersion compensation of long haul optical systems
Optics Express, 2006Co-Authors: A J Lowery, Jean ArmstrongAbstract:We show using simulations that a combination of Orthogonal Frequency Division Multiplexing (OFDM) and Optical Single Sideband Modulation (OSSB) can be used to adaptively compensate for chromatic dispersion in ultra-long-haul 10 Gbps Standard Single-Mode Fiber (S-SMF) links. Additionally, for optical noise limited systems with Forward-Error Correction, OFDM can tolerate an Optical Signal to Noise Ratio (OSNR) 0.5 dB higher than NRZ systems providing the optical carrier is suppressed.

10 gbit s multimode fiber link using power efficient orthogonal Frequency Division Multiplexing
Optics Express, 2005Co-Authors: A J Lowery, Jean ArmstrongAbstract:Orthogonal Frequency Division Multiplexing (OFDM) can provide electronic dispersion compensation of optical paths. However, it requires a high bias to convert bipolar electrical signals to unipolar optical signals, so is inefficient in optical power for a given electrical signal to noise ratio. We present a novel method of transmitting OFDM signals over multimode fibers that increases electrical SNR by 7 dB for a given optical power. Using simulations, we show a 1.8 dB sensitivity benefit over 10 Gbit/s NRZ (Non-Return to Zero) and demonstrate compensation of inter-modal dispersion in a 300-m multimode fiber that cannot support NRZ.

Frequency response enhancement of direct detection phase sensitive otdr by using Frequency Division Multiplexing
Journal of Lightwave Technology, 2018Co-Authors: Guangyao Yang, Xinyu Fan, Qingwen LiuAbstract:The Frequency Division Multiplexing (FDM) technique is first introduced into a direct-detection phase-sensitive OTDR to improve the distributed acoustic sensing performance by using a Frequency step sweeping laser source and a dual-pulse heterodyne detection scheme. A raised-cosine-shaped pulse is used to suppress the crosstalk in the FDM technique. By using this technique, a 40-kS/s sampling rate to vibration is realized with a 10-km measurement range, which implies the tradeoff relationship between the Frequency response and the measurement range is broken. In the experiment, vibrations with different frequencies are measured to validate the effectiveness of the proposed technique. A 20-kHz Frequency response is achieved over a 10-km measurement distance, and the Frequency response shows a good flatness with a fluctuation of $\sim$ 0.5 dB.
