Abstract

A Y-branch directional coupler modulator based on electro-optic (EO) polymer with domain-inversion is designed, fabricated, and characterized. The functional core material is LPD-80 chromophore in amorphour-polycarbonate (APC) host polymer which is cladded between UV15-LV and UFC-170A. The switching voltage of 4.4V and the electro-optic coefficient (r₃₃) of 90pm/V are measured from 4-domain directional coupler modulator and Mach-Zehnder modulator, respectively. A two-tone test of domain-inversed directional coupler modulator demonstrates the spurious-free dynamic range (SFDR) of 119dB/Hz^2/3, which is enhanced by 11dB compared with the conventional Mach-Zehnder modulator. The SFDR of Mach-Zehnder modulator shows good agreement with simulation result but the directional coupler modulator shows approximately 10dB lower value than simulation result, which is mainly due to the high sensitivity of directional coupler structure to the fabrication error. Further improvement can be achieved with completion of fabrication precision.
