Claim Text:
1. A device for generating an optical communication signal comprising: a coupler that splits an input signal into a first signal and a second signal; an envelope tracker that generates an envelope tracking signal proportional to a time varying power envelope of the first signal; an average power detector that generates an average power signal corresponding to an average power of the first signal; a microcontroller to generate a plurality of control signals based on the envelope tracking signal and the average power signal; a variable attenuator coupled to the coupler to generate an attenuated signal corresponding to the second signal in response to a first control signal in the plurality of the control signals; a laser bias controller that generates a laser bias current in response to a second control signal in the plurality of the control signals; and a laser module coupled to the variable attenuator and the laser bias controller that generates the optical communication signal corresponding to the input signal and in response to the attenuated signal and the laser bias current.
