Abstract

A feedforward over an analog optical link is known as difficult technique in spite of its superior linearization. We proposed a broadband analog feedforward optical transmitter using a wideband 180° hybrid coupler instead of conventional frequency-sensitive phase shifter with the narrow bandwidth property. Using the wideband 180° hybrid coupler, the wideband linearization technique enhances the wide operation frequency and simple adjustment of the feedforward optical transmitter. Our experimental results show the 3^rd-IMDs enhancement more than 10 dB at 385 MHz range (1.375~1.76 GHz).
