Claim:
1. An optical communication system, comprising: a photodiode configured to receive light energy and convert the light energy into an electrical signal; a first amplification stage that receives the electrical signal output by the photodiode and produces a first amplified output of the electrical signal received from the photodiode; a second amplification stage that receives the first amplified output of the first amplification stage and produces a second amplified output of the first amplified output received from the first amplification stage; a gain controller that controls a gain of the second amplification stage based on a control signal input to the second amplification stage; and at least one capacitive element that extends a bandwidth of the second amplified output at a maximum gain of the second amplification stage and also reduces a peaking of the second amplified output at a minimum gain of the second amplification stage.
