摘要:
A waveguide. The waveguide may include a first waveguide region that includes a signal trace with a first width. The waveguide may further include a second waveguide region that includes the signal trace with a second width. The first width may be different from the second width. The signal trace may be configured to transmit an electrical signal. The signal trace with the second width may be configured to couple with an integrated circuit.

An active device lid for a device base. The device lid includes a heatsink proximate to a circuit assembly and configured to remove heat generated by the device base, the circuit assembly configured to generate an operating signal voltage for the device base, and a connector configured to connect the circuit assembly to the device base, where the device base is configured to connect to a device mounting substrate on a substrate side of the device base, and where the circuit assembly is configured to be at least partially located on an opposing side of the device base, the opposing side opposing the substrate side.

摘要:
A tuning system for use in a receiver of an optical transmission system. The receiver includes a data channel transporting a data signal and a monitoring channel transporting a copy of the data signal. The tuning system includes a processing module for processing the copy of the data signal to generate a control signal conveying tuning information. This tuning information is used by the receiver to alter an operating point of the receiver on the data channel. The operating point of the receiver that is susceptible to be altered by the control signal is a decision threshold applied on the data signal to discriminate one binary value from another binary value on the data channel of the receiver. This approach allows, when required or desired, tuning of the system while the system is in service. This is possible since the tuning of the system is performed using the monitoring channel, and does not disturb nor corrupt the actual data being transported on the data channel.
