High-speed AJL8/APC polymer modulator

High-speed polymer modulators were fabricated using low-V/sub /spl pi// AJL8 chromophore in amorphous polycarbonate, and highly calibrated frequency response measurements were obtained using convenient coplanar-microstrip transitions. These Mach-Zehnder modulators show good frequency response to 50 GHz, with a loss and velocity mismatch-limited V/sub /spl pi// at 50 GHz <12 V. The measurements establish AJL8 as an excellent candidate for future military analog optical links.
