  • All-optical CDMA with bipolar codes 

    Nguyen, Lim; Aazhang, Behnaam; Young, James F. (1995-03-20)
    A method for the transmission and detection of bipolar sequences in a unipolar system is presented. It allows all-optical implementation, in noncoherent optical CDMA systems, of the bipolar codes that have been developed ...
  • BER of optical communication system using fiber source 

    Nguyen, Lim; Aazhang, Behnaam; Young, James F. (1995-11-20)
    We analyze the bit-error rate (BER) of an optical communication system using the superfluorescent fiber source (SFS). The counting statistics of thermal light give improved performance relative to the Gaussian statistics ...
  • Experimental demonstration of bipolar codes for direct detection multi-user optical communication 

    Dennis, Tasshi; Nguyen, Lim; Aazhang, Behnaam; Young, James F. (1996-10-20)
    We report the first experimental demonstration of a broadband spectral encoding and decoding technique using bipolar codes for optical code-division multiple access. The codeword correlations are verified and rejection of ...
  • Principle and practice of optical code-division multiple access communication 

    Nguyen, Lim (1996)
    This research examines the theoretical and experimental aspects of code-division multiple access (CDMA) communication in the incoherent, or direct detection, optical domain. We develop new modulation and detection principles ...
