    • A photonic transmitter, comprises a modulator driver having a first and second output ports, a photonic integrated transmitter circuit having a modulator having a first and a second input line, and a first input port electrically coupled with the first input line and a second input port electrically coupled with the second input line, and an interconnect bridge assembly, including a first termination resistor, a second termination resistor, and a substrate. An impedance-controlled transmission structure is formed in the substrate, and has: (a) an impedance control section including a first and a second signal lines electrically insulated from one another; and (b) a transmission section including a third and a fourth signal line coupled with termination resistor. The interconnect bridge assembly transmits an impedance controlled differential electrical signal from the modulator driver to the modulator, and transmits the electrical signal from the modulator to the first and second termination resistors.

    • One embodiment contemplates a polarization insensitive optical circuit constructed of an input/output signal separator, such as an optical circulator or a 1×2 or 2×2 coupler or N×M coupler, a polarization sensitive operator, and a polarization rotator reflector. In an alternate embodiment, the invention contemplates a polarization insensitive optical circuit including a polarization rotator reflector, and a polarization sensitive operator which may include, for example, a first polarization rotator, an operator/coupler, and a polarization beam combiner. Preferably, at least one of the components in the optical circuit is constructed integrally from the substrate upon which the optical circuit is based. For examples the polarization rotator and/or polarization sensitive operator may be monolithic.
