High-power UV light generation in picosecond pulse trains

Mikhail Martyanov; Marta Divall; Ekaterina Gacheva; Christoph Hessler; Valentin Fedosseev 2013 Conference on Lasers & Electro-Optics Europe & International Quantum Electronics Conference CLEO EUROPE/IQEC, 2013

This paper focuses on the investigation of detrimental UV induced effects during fourth harmonic generation (FHG) in BBO crystals. An accumulation of partly recoverable UV two-photon induced optical defects has been observed in the 140 s train generated by frequency quadrupled 1.5 GHz Nd:YLF laser with about 300 W UV power per train, even for a relatively low peak pulse ...

Downlink SINR Statistics in OFDM-Based Optical Attocell Networks with a Poisson Point Process Network Model

Cheng Chen; Dushyantha Basnayaka; Harald Haas 2015 IEEE Global Communications Conference (GLOBECOM), 2015

In this paper, the downlink signal-to-interference- plus-noise ratio (SINR) statistics are analysed in a direct current-biased optical orthogonal frequency division multiplexing (DCO-OFDM) based optical attocell network with a Poisson point process (PPP) cell deployment. An optical attocell system utilises existing lighting fixtures in an indoor environment to function as a small-cell cellular network. It uses each luminary as a base ...

A 16 Gb/s electrically time-division-multiplexed lightwave link is discussed. The 16 Gb/s electronic signal was generated by multiplexing together eight copies of the 2-Gb/s pseudorandom sequence (length 2/sup 15/-1) produced by a commercial BER test set. A 22-km transmission distance was achieved using a directly modulated, 1.3- mu m wavelength DFB laser and a 50- Omega p-i-n receiver. Receiver sensitivity ...

  • Multiuser CDMA Fi-Wi Systems

    A multiuser CDMA fiber-wireless system will experience all the following impairments: (1) nonlinear distortions in the optical channel; (2) multipath dispersion in the wireless channel; and (3) multiuser interference in the air interface. Optical and electrical noise will also be added in both channels. In addition, each user will experience individual multipath fading while the nonlinear distortion would be a function of total number of users in the system because nonlinear optical channel is shared among them. This chapter shows how all these impairments can be estimated and equalized using a very interesting iterative technique. This algorithm could add value for fourth generation (4G) wireless networks.

  • Exercises and Simulation Examples Contained in the CDROM

    Optical Bit Error Rate: An Estimation Methodology provides an analytical methodology to the estimation of bit error rate of optical digital signals. This presents an extremely important subject in the design of optical communications systems and networks, yet previous to the publication of this book the topic had not been covered holistically. The text lays out an easy- to-understand analytical approach to a highly important and complex subject: bit error rate (BER) estimation of a transmitted signal with a focus on optical transmission. It includes coverage of such important topics as impairments on DWDM optical signals, causes of signal distortion, and identification and estimation of the signal quality by statistical estimation of the bit error rate. The book includes numerous illustrations and examples to make a difficult topic easy to understand. This edition includes a CD-ROM with run-time simulations from a vendor that provides commercial software for the industry.

  • Subcarrier-Multiplexed ROF Downlink

    Chapter 5 provides detailed analysis of a fiber-wireless forward link when more than one multiuser RF signals are transmitted over fiber. Wi-Fi and cellular radio signals are considered. The concept of nonlinearity induced co- channel interference is introduced in this chapter. Detailed mathematical expressions are derived for signal to distortion, noise and (multiuser) interference ratios for both wireless systems considering optical link nonlinearity and wireless channel fading. Simulation results are also shown.

  • Joint Equalization for the Fi-Wi Channel

    When nonlinear distortion of the fiber channel and the multipath dispersion of the wireless channel are combined together, equalization is a very interesting challenge. These two distortions have to be dealt jointly when the baseband DSP approach is used. In this chapter a novel algorithm is developed to equalize the both the static nonlinearity of the optical channel and the dynamic multipath dispersion of the wireless channel. A patented equalizer structure is described that compensates for the linear and nonlinear portions separately.

  • Direct Modulation for Microwave Photonics

    This chapter contains sections titled: Introduction to Direct Modulation for Microwave Photonics Review of Semiconductor Laser Devices RF Signal Strength and Optical Link Gain Signal Bandwidth and High-speed Lasers Signal Distortion and Spurious Free Dynamic Range Low-cost VCSEL RF Photonic Links Cascade Laser Optical Links References

  • Joint Estimation of the Fi-Wi Channel

    It is an interesting scenario when the nonlinear distortion of the fiber channel and the multipath dispersion of the wireless channel are combined together. These have to be dealt jointly when the baseband DSP approach is used due to the concatenated nature of the fiber-wireless channel. Note that there is no down conversion done at the radio access point therefore no baseband DSP is possible. In this chapter a novel algorithm is developed to estimate both the nonlinearity coefficients of optical channel as well as impulse response of the wireless channel by observing the input output digital signals.

  • Subcarrier-Multiplexed ROF Uplink

    Chapter 6 provides detailed analysis of a fiber-wireless reverse link when more than one multiuser RF signals are transmitted over fiber. The concept of nonlinearity induced co-channel interference is explained in this chapter and detailed expressions for signal to distortion, noise and (multiuser) interference ratios are derived for both wireless systems considering optical link nonlinearity and wireless channel fading. Simulation results are also shown. Note that the reverse link is asynchronous compared forward link.
