1. A method comprising:
providing a multilayer substrate with a substrate top and a substrate bottom;
positioning an optoelectronic transducer on the substrate top;
positioning at least one driver on the substrate top;
positioning a controller directly against the substrate bottom;
electrically coupling the controller with the driver with at least one via extending through multiple layers of the multilayer substrate; and
electrically coupling the driver and the optoelectronic transducer with at least one signal line on the substrate top such that the controller sends control signals to the driver and the optoelectronic transducer.
