Abstract
The Franz-Keldysh effect is utilized for high-linearity, electroabsorptive InGaAsP waveguide modulators. Two-tome RF measurements are performed in which the DC bias is adjusted to maximize the spurious-free linear dynamic range. With the proper choice of bias, the sub- octave link dynamic range increases to 123 dB in a 1 Hz bandwidth for 0.25 mA photocurrent.
