The paper presents the development and optimization of ultra-broadband photodiodes (> 100 GHz) and balanced photodetectors (70 GHz). These developments are based on the waveguide-integrated photodiode type applying semi-insulating optical waveguide layers, grown on InP:Fe. The chip developments, characterizations in the frequency and time domain and the packaging of the chips into modules with fibre pigtail and 1 mm connector are described. The modules are tested at bit rates of 80, 100 and 160 Gbit/s, employing NRZ, RZ and DPSK modulation formats.
