Abstract :
In summary we fabricated and characterized integrated differential photodetector modules with 35 GHz and 45 GHz electrical bandwidth. The devices show total responsivities of 0.41 A/W and 0.31 A/W respectively and PDL of less than 0.5 dB. The ratio of the photocurrents remains below 0.5 dB for different states of polarization demonstrating an excellent electrical and optical symmetry. The modules deliver high electrical output pulses of differential polarity in the 1 Volt regime to switch directly all known 40 Gbit/s demux electronics implemented in SiGe, GaAs or InP technology.
