Plasmonic crystals with sharp Optical Transmission behaviors
Materials Letters, 2016Co-Authors: Zhengqi Liu, Zhenping Huang, Jian ChenAbstract:Abstract In this work, we for the first time propose and demonstrate a feasible strategy for multi-band ultra-narrow Optical Transmission of the plasmonic crystals by introducing a high-index dielectric (HID) cavity, which can be acted as an efficient Optical field coupling and hybridization component. Five sharp Transmission bands with the maximal bandwidth of 6.5 nm are achieved. High spectral Q-factor of 327 with the corresponding bandwidth of 2.8 nm is observed in the Optical region. These features pave a simple and universal way for multispectral narrowband Optical Transmission based on the typical plasmonic crystals.

Error statistic of QAM channel in AM/QAM hybrid Optical Transmission
IEEE Photonics Technology Letters, 1996Co-Authors: K. Maeda, K. Utsumi, K. FujitoAbstract:The error statistic of the QAM channel in an AM/QAM hybrid Optical Transmission system is measured. Errors occur randomly in Optical Transmission without clipping. However, errors are found to occur in bursts when the impulsive noise due to clipping degrades the QAM signal's BER. The error statistic is critical to properly designing the error correction employed in the hybrid system.

ICC - Multilevel Coding for Spectrally Efficient Noncoherent Optical Transmission
2006 IEEE International Conference on Communications, 2006Co-Authors: Ivan B. Djordjevic, Bane VasicAbstract:Transmitter and receiver configurations suitable for M-ary DPSK/differential QAM noncoherent Optical Transmission are proposed. It is shown that multilevel coding based on lowdensity parity-check codes as component codes is an efficient approach to achieve high-spectrally efficient noncoherent Optical Transmission. The multilevel coding scheme with 2 bits/s/Hz spectral efficiency based on block-circulant component codes provides the coding gain of 12.3 dB compared to uncoded 8-DPSK, and 8.3 dB compared to uncoded QDPSK.

Optical Transmission properties of perforated metal films in the middle-infrared range
Applied Physics Letters, 2009Co-Authors: Yurong Cao, Zhi-bing Wang, Desheng Yan, Jia-yu ZhangAbstract:We experimentally studied the enhanced Optical Transmission of perforated silver films in the middle-infrared region. The Optical Transmission properties of the samples with classical inductive frequency selective surface structures are also affected by both the periodicity and the aperture shape. Our results indicate that the physical operating mechanisms are the same for the plasmon crystal and the frequency selective surface, and both surface plasmon polaritons due to the periodicity and waveguide modes that are present in single holes have effect in the Optical Transmission enhancement.
