Matching circuits on optoelectronic devices

1. An apparatus comprising:

a first substrate;

an optoelectronic device formed on the first substrate, the optoelectronic device having a frequency response;

a matching circuit formed on the first substrate and coupled to the optoelectronic device to change its frequency response;

a driver circuit that communicates with and controls the optoelectronic device;

a second substrate, wherein the driver circuit is formed on the second substrate;

wherein the matching circuit is selected to match the frequency response of the optoelectronic device to the drive circuit for optimal performance;

wherein the optoelectronic device is flip-chip mounted to an auxiliary circuit.

2. An apparatus comprising:

a first substrate;

an optoelectronic device formed on the first substrate, the optoelectronic device having a frequency response;
