Abstract :
By incorporating dual-depletion-region electroabsorption modulator with an evanescently-coupled waveguide, the demonstrated device can achieve low electrical return-loss (<-22dB), wide electrical 3-dB transmission-loss bandwidth (~70 GHz), wide electrical-to-optical bandwidth (>45 GHz), and low-driving-voltage (V20dB, 1.65 V) with small polarization-dependency.
