1 April 1993 Quasi-feed-forward linearization of electro-optic modulators for analog signal transmission
Author Affiliations +
A quasi-feed-forward (QFF) linearization scheme for use with electro-optic modulators is presented. This scheme provides an increase in the intermodulation-free dynamic range of the modulator as well as substantial cancellation of laser relative intensity noise (RIN) of the cw source. The results of this investigation indicate that such a scheme is adequate for the transmission of 100 or more Canadian television channels transmitted in a vestigial sideband AM format using a cw source with a RIN of only - 130 dB/Hz. A tolerance analysis has been performed to predict the effects of a nonideal practical implementation.
