Low RF crosstalk devices via a slot for isolation

Abstract:

An apparatus includes a plurality of layers arranged on top of one another and including at least one ground layer and a signal layer; a first set of signal pads and a second set of signal pads on the signal layer; and a slot formed in the at least one ground layer between the first set of signal pads and the second set of signal pads. The apparatus can include an optical assembly housed by the plurality of layers and connected to the first set of signal pads and the second set of signal pads. The optical assembly can include a micro Intradyne Coherent Receiver (.mu.ICR), a Coherent Driver Modulator (CDM), or a Coherent Optical Subassembly (COSA).
