Abstract :
A linearized directional coupler modulator based on electrooptic polymer was fabricated and tested. The linearity was obtained by tailoring the coupling coefficient of the device using the photobleaching technique. A two-tone test of the device was presented and it demonstrated an enhancement in intermodulation distortion compared to a Mach-Zehnder modulator.
