Monolithic optical gates based on integration of evanescently-coupled uni-traveling-carrier photodiodes and electroabsorption modulators

doi:10.1088/1674-1056/19/7/074216

Abstract We report on chip-scale optical gates based on the integration of evanescent waveguide unitraveling-carrier photodiodes (EC-UTC-PDs) and intra-step quantum well electroabsorption modulators (IQW-EAMs) on n-InP substrates. These devices exhibit simultaneously 2.1 GHz and -16.2 dB RF-gain at 21 GHz with a 450 Ω thin-film resistor and a bypass capacitor integrated on a chip.

Keywords: electroabsorption modulator intra-step quantum wells uni-traveling-carrier RF-gain
