Matching circuits on optoelectronic devices

1. An apparatus comprising:

a substrate, an optoelectronic device and a matching circuit formed on the substrate, the optoelectronic device having a frequency response and the matching circuit configured to change the frequency response; and

a driver formed separate from the substrate, the driver configured to control the optoelectronic device within a desired frequency range, wherein the substrate is selectively flip-chip coupled to the driver via bond pads on the substrate such that the matching circuit is interposed between the optoelectronic device and the driver.

2. An apparatus as in claim 1 , wherein the matching circuit is selected to match the frequency response of the optoelectronic device to the driver for optimal performance.

3. An apparatus as in claim 2 , wherein the optoelectronic device is a Vertical Cavity Surface Emitting Laser (VCSEL).

4. An apparatus as in claim 2 , wherein the optoelectronic device is an edge-emitting diode.

5. An apparatus as in claim 2 , wherein the matching circuit includes a passive device from the group consisting of inductors, capacitors, resistors, stubs, and diodes.

6. An apparatus as in claim 1 , wherein the driver comprises an amplifier that communicates with and amplifies a signal from the optoelectronic device.

7. An apparatus as in claim 6 , wherein the matching circuit comprises multiple stages.

8. An apparatus as in claim 7 , wherein a select number of stages are coupled between the optoelectronic device and the amplifier.

9. An apparatus as in claim 8 , wherein the matching circuit includes a passive device from the group consisting of inductors, capacitors, resistors, stubs, and diodes.

10. An apparatus as in claim 2 , wherein the optoelectronic device is a photosensor.

11. An apparatus as in claim 10 , wherein the photosensor is flip-chip mounted to the amplifier.
