Abstract
We experimentally demonstrate a linearized Y-fed directional coupler (DC) modulator based on an electro-optic (EO) polymer waveguide. The spurious free dynamic range of , which is higher than that of the conventional Mach–Zehnder modulator, is achieved by introducing the reversed technique in the two-section Y-fed DC. The in-device EO coefficient () of the fabricated device is as high as in wavelength, which is 88% of a single film of LPD-80/APC
