Abstract: This disclosure concerns systems and devices configured to implement impedance matching schemes in a high speed data transmission environment. In one example, an optoelectronic assembly is provided that includes a TO package having a base through which one or more leads pass. The leads are electrically coupled to an optoelectronic device in the TO package, and are electrically isolated from the base. Some or all of the leads include a ground ring that is electrically isolated from the lead and electrically coupled with the base. A circuit interconnect is also included that is electrically coupled to the optoelectronic device and the TO package. The circuit interconnect includes a dielectric substrate having signal traces that are electrically coupled to the signal leads. A ground signal conductor disposed on the dielectric substrate is electrically coupled with the ground rings.

Abstract: The present invention relates generally to laser diodes, and particularly to an operational amplifier able to switch laser diodes on and off quickly without adversely affecting data transmission by the laser diodes. A differential amplifier included in an operational amplifier has a high transconductance when a laser diode is first turned on and a low, near constant transconductance when the laser diode is transmitting data. The operational amplifier is preferably incorporated in optoelectronic transceivers used in passive optical networks. Switching laser diodes on and off quickly enables more efficient use of network bandwidth in such passive optical networks.

Abstract: An optoelectronic assembly includes a circuit board having a set of signal traces, where one or more of the signal traces has a junction point that integrates a pad of a circuit element. Exemplary circuit elements include a resistor, capacitor, and an inductor. The junction point has a first width and a first thickness, and the one or more signal traces have a second width and a second thickness. The dimensions of the junction point and the dimensions of the one or more signal traces are configured such that the first width and the second width are substantially similar, and that the first thickness and the second thickness are substantially similar. In one embodiment, the first width is no greater than 125% of the second width.

Abstract: An optical transmitter and/or a constituent electro-optic transducer driver that performs active matching. The transducer driver performs active matching using a voltage step down through one base-emitter bipolar transistor, followed by a step up approach through the base-emitter of another bipolar transistor, thereby allowing for lower supply voltages. Furthermore, the voltage drop across the source resistor is minimal by using an operation amplifier in a feedback configuration, thereby further encouraging operability with low supply voltages. The electro-optic transducer driver is also beneficial in that it has high AC-coupling efficiency of the modulation current to the electro-optic transducer, may operate at high speeds with reduced jitter.
