Abstract
An electroabsorption modulated laser (EML) is linearized by emulation and reversal of the nonlinear distortion using a companion EML inside an optoelectronic interferometer, Suppression of composite second-orde r and triple-beat signals to < -61 and < -63 dBc, respectively, have b een achieved for a carrier-to-noise ratio (CNR) of 50 dB with a 77-cha nnel loading of CATV carriers, Further performance enhancement can be expected through tailoring of device and component characteristics to suit the application.
