Abstract: Performance of a photonic integrated circuit (PIC) is improved by using at least one electro-optic (EO) device included in the PIC to perform at least one EO conversion operation whereby an information signal is transitioned from a first signal carrier type to a second signal carrier type different from the first signal carrier type. The first and second signal carrier types are selected from the group consisting of an optical signal carrier and an electrical signal carrier. An operating bandwidth of the PIC is increased by performing electrical signal impedance matching operations directly on the at least one optical media substrate. An improved electrical impedance match is thus obtained between the EO device and a second device exclusive of the PIC.

Abstract: Active optical cable (AOC) includes at least one optical fiber constituting a signal transmission medium and a plurality of optical data transceivers disposed at separate connector ends of the AOC assembly. The AOC includes a common laser source in a common laser hub (CLH) providing a source optical signal to the optical data transceivers. The optical data transceivers modulate the source optical signal to form modulated optical data signals. In some scenarios described herein, the CLH is disposed at an intermediate location along a length of the AOC between the separate connector ends of the AOC. Further, a central processor can be provided in the CLH to facilitate consolidated data processing operations for the plurality of optical data transceivers.
