  • Patent number: 10148357
    Abstract: Non-ideal downstream loading of a differential driver in a single ended circuit driving a communications laser—e.g., Electro absorption Modulated Laser (EML)—may be compensated by deploying a second matching network at the non-functional (terminated) driver output node. Certain embodiments may further compensate for distortion arising from circuit non-ideality, by introducing a laser replica downstream of the second matching network to mimic electrical properties of the laser. Embodiments may sufficiently compensate for downstream circuit non-ideality to allow replacing the bulky choke inductor of a bias tee, with a resistor. Substituting a resistor for a more complex inductor structure can simplify design and fabrication of the single-ended driver circuit, and also reduce footprint by eliminating area formerly occupied by the choke inductor.
