Specific Features of XGM in QD-SOA

Y. Ben Ezra; B. I. Lembrikov; M. Haridim IEEE Journal of Quantum Electronics, 2007

The peculiarities of a cross-gain modulation (XGM) in quantum-dot semiconductor optical amplifier (QD SOAs) related to the inhomogeneous broadening are theoretically studied. We have solved numerically the electron rate equations for the QD SOA model including an excited state, a ground state and a continuum wetting layer (WL), and the propagation equations for the pump and the signal lightwaves.

We developed an analog 60-GHz module for RF/optic conversion by using an electroabsorption modulator (EAM) device associated with a traveling-wave electrode. The impedance matching of the module was accomplished with the 30-Ω termination such that the resonance was precisely located at 60 GHz and the fractional bandwidth at S11=-15 dB was as large as 1.0 GHz. The RF/optic conversion gain ...


Optical Domain Down-Conversion of Microwave Signals for High Dynamic Range Microwave Fiber Optic Links

Yifei Li; P. Herczfeld; A. Rosen; M. Bystrom; Tibor Berceli 2006 International Topical Meeting on Microwave Photonics, 2006

Optical downconversion of microwave signals offers the potential for reduced noise and higher dynamic range over electronic downconversion. A novel downconversion scheme is introduced which allows for remote reception of microwave signals and downconversion to intermediate frequencies or baseband in the optical domain. Experiments show low noise and intermodulation effects. Further extensions of the optical downconverter and potential gains are ...

  • 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.

  • 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.

  • 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.

  • 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.
