Abstract: Embodiments herein describe optical assemblies that use a spacer element to attach and align a laser to a waveguide in a photonic chip. Once aligned, the laser can transfer optical signals into the photonic chip which can then perform an optical function such as modulation, filtering, amplification, and the like. In one embodiment, the spacer element is a separate part (e.g., a glass or semiconductor block) that is attached between the photonic chip and a submount on which the laser is mounted. The spacer establishes a separation distance between the photonic chip and the submount which in turn aligns the laser with the waveguide in the photonic chip. In another embodiment, rather than the spacer element being a separate part, the spacer element may be integrated into the submount.

Abstract: Embodiments herein describe an electro-optic waveguide having a multi-mode multi-pass phase shifter (MMPS) tuner, one or more two-mode Bragg gratings, and one or more selective evanescent couplers. An input signal having a fundamental mode is reflected by the one or more Bragg gratings and tuned by the MMPS tuner. In this manner, the electro-optic waveguide isolates the higher order modes of the input signal. The one or more selective evanescent couplers capture an output signal having the highest order mode and reduces the mode of the output signal to the fundamental mode.

Abstract: A pluggable device and method are presented. The pluggable device includes a substrate, a first pin positioned on the substrate, an optical source positioned on the substrate, and an integrated circuit positioned on the substrate. The optical source produces a source optical signal and transmits the source optical signal through the first pin. The integrated circuit transmits a received optical data signal and transmits a data signal based on a portion of the optical data signal.

Abstract: 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.

Abstract: 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.
