Abstract
An optical device has a photodiode placed on a substrate. A guide is formed on the substrate so that it surrounds the photodiode with concentric positioning to an accuracy better than 5 μm. A ferrule of a ferrule assembly engages within the guide for automatic alignment with the photodiode without need for active alignment with monitoring of light signals.
