Abstract
In this paper, we demonstrate a traveling wave linear modulator for high speed
analog optical link applications. A two-section Y-fed directional coupler modulator
based on electro-optic polymer is linearized with Δβ -reversal technique to
suppress the third-order intermodulation distortions. A traveling wave electrode with
low RF loss and excellent velocity matching is designed and demonstrated with the
bandwidth-length product of 125 GHz·cm. The 3-dB electrical bandwidth of 10 GHz
and the spurious free dynamic range of 110 ± 3 dB/Hz<sup>2/3</sup> over the modulation
frequency of 2–8 GHz are measured form the fabricated device.
