We designed and fabricated receiver modules with an optimized fiber-chip coupling set-up and high electrical bandwidth up to 45 GHz. The set-up is suited as well for high volume production and also for rapid prototyping of waveguide-fed InP and GaAs OEICs with optical spot size expanders. The light output of these OEICs is collected with high efficiency into butt-ended single mode fibers. The fabricated photodiode modules are ready for usage in 40 Gbit/s lightwave systems.
