Patent ID: 7277463

Claim:
An optoelectronic device comprising: a VCSEL, the VCSEL comprising: a VCSEL top mirror; an active region coupled to the VCSEL top mirror; and a VCSEL bottom mirror; a transition region coupled to the VCSEL; a photodiode coupled to the transition region; and metal coupled to the optoelectronic device so as to short at least a portion of the transition region and to provide Ohmic contacts to the VCSEL and photodiode, wherein the transition region and photodiode comprise: an N+ GaAs layer coupled to the VCSEL; a GaAs or AlGaAs layer coupled to the N+ GaAs layer; a P+ GaAs layer coupled to the AlGaAs layer; a P+ GaAs or AlGaAs layer coupled to the P+ GaAs layer; and an N type absorption layer coupled to the P+ GaAs or AlGaAs layer.
