    Abstract: A bidirectional optoelectronic device comprises a photodetector, a light source, and a drive circuit for the light source. The light source has first and second electrical leads for receiving an input electrical signal, and the drive circuit can be arranged to apply first and second portions of the input electrical signal to the first and second electrical leads, respectively, wherein the second portion of the input electrical signal is a scaled, inverted substantial replica of the first portion of the input electrical signal. A protective encapsulant can be applied that includes hollow dielectric microspheres to reduce electrical cross-talk, and that can further include an optical absorber to reduce optical cross-talk. A waveguide substrate of the device can include light collector(s) or trap(s) for redirecting and attenuating portions of optical signals propagating in waveguide layers on the substrate but not guided by a waveguide.
