摘要： An optical module includes an optical source, a first polarization splitter-rotator, a second polarization splitter-rotator, a first port, a second port, a third port, and a fourth port. The optical source produces an optical signal. The first polarization splitter-rotator generates a first source optical signal based at least in part on the optical signal. The second polarization splitter-rotator generates a second source optical signal based at least in part on the optical signal. The first port transmits, to a first device, the first source optical signal and receives, from the first device, a first modulated optical signal. The first polarization splitter-rotator produces a second modulated optical signal. The second port transmits, to a second device, the second source optical signal and receives, from the second device, a third modulated optical signal. The second polarization splitter-rotator produces a fourth modulated optical signal.

摘要： A system, method, and photonic chip for an optical circulator are described. The system includes a first polarization splitter, a first optical circuit, and a first controller. The first polarization splitter receives, at a first port of the first polarization splitter, a first optical signal. The first optical circuit is optically coupled to the first polarization splitter. The first optical circuit includes a first plurality of phase shifters. The first optical circuit receives, at a first port of the first optical circuit, a second optical signal. The first controller adjusts the first plurality of phase shifters such that the first optical circuit outputs the first optical signal at a second port of the first optical circuit and such that the first polarization splitter outputs the second optical signal at the first port of the first polarization splitter.

摘要： A system includes a first device and a second device. The first device generates a source optical signal using a first optical signal and a polarization splitter-rotator. The second device modulates the source optical signal from the first device using a first data signal to produce a first modulated optical signal. The first modulated optical signal has a polarization that is orthogonal to a polarization of the source optical signal. The first device recovers the first data signal from the first modulated optical signal using at least the polarization splitter-rotator.

摘要： An electrical connector for connecting to an array of surface contacts includes a connector body and a plurality of cable terminators. The connector body defines an interior volume and includes an external surface defining a plurality of cable openings each configured to receive a respective multi-conductor cable therethrough and a plurality of passageways. The plurality of cable terminators are each configured to couple with a respective multi-conductor cable exiting the second section of a respective passageway. Each cable terminator includes a plurality of pins each configured to couple with a respective conductor of the multi-conductor cable and to extend to a respective contact surface. The contact surfaces of the plurality of cable terminators extend to a second plane. The first plane and the second plane are coplanar when the array is in the connection position.
