采用一种简单、高产量的软模复制成型技术制备了马赫-曾德尔型电光聚合物振幅调制器。调制器结构采用了高度非线性和稳定的发色团，AJL 8，掺杂在无定形聚碳酸酯。单臂相位延迟导致在1600 nm处的8.4 V的半波电压（V-pi）。由于采用了精确的Y分支功分器和良好的波导均匀性，开关消光比优于19 dB。这些结果表明，简单的制造工艺允许从原始主器件的高保真复制品获得良好的光学性能。
A Mach-Zehnder electro-optic polymer amplitude modulator is fabricated by a simple and high-throughput soft-stamp replica-molding technique. The modulator structure incorporates the highly nonlinear and stable chromophore, AJL8, doped in amorphous polycarbonate. Single-arm phase-retardation results in a halfwave voltage (V-pi) of 8.4 V at 1600 nm. The on/off extinction ratio is better than 19 dB, resulting from precise Y-branch power splitters and good waveguide uniformity. These results indicate that the simple fabrication process allows for good optical performance from high-fidelity replicas of the original master devices.
