Abstract
An optical receiver is disclosed having a dielectric non-conductive substrate. A ground plane is positioned on the dielectric non-conductive substrate. An optical signal converting photodiode is also positioned on the dielectric non-conductive substrate, and has an optical signal receiver and an electrical signal output. An electrical signal amplifier is provided having an input connected to the electrical signal output of the optical signal converting photodiode. A first opening is positioned in the ground plane and surrounds the optical signal converting photodiode. The first opening has a resonance frequency higher than a fundamental frequency such that crosstalk is reducible at the input of the electrical signal amplifier.
