Abstract
In one embodiment, an apparatus for a high data-rate optical modulator bias circuit is disclosed. The apparatus comprises an optical modulator, a voltage-controlled voltage source to translate a control voltage into a voltage referenced to a voltage supply to the optical modulator, a buffer amplifier with high current sinking capability to supply a bias voltage to the optical modulator, and a bias-T to couple the bias voltage to a data port of the optical modulator. Other embodiments are also described.
