    Abstract: An optical system includes a first optical source, a second optical source, a first optical modulator, and a second optical modulator. The first optical modulator includes a first input and a first output. The second optical modulator includes a second input, a third input, a second output, and a third output. During a first mode, the first optical source emits a first optical signal to the first input and the second input, the first optical modulator produces a first modulated optical signal at the first output, and the second optical modulator produces a second modulated optical signal at the second output. During a second mode, the second optical source emits a second optical signal to the third input and the second optical modulator produces a third modulated optical signal at the third output.

    Abstract: Methods and systems for a vertical junction high-speed phase modulator are disclosed and may include a semiconductor device having a semiconductor waveguide including a slab section, a rib section extending above the slab section, and raised ridges extending above the slab section on both sides of the rib section. The semiconductor device has a vertical pn junction with p-doped material and n-doped material arranged vertically with respect to each other in the rib and slab sections. The rib section may be either fully n-doped or p-doped in each cross-section along the semiconductor waveguide. Electrical connection to the p-doped and n-doped material may be enabled by forming contacts on the raised ridges, and electrical connection may be provided to the rib section from one of the contacts via periodically arranged sections of the semiconductor waveguide, where a cross-section of both the rib section and the slab section in the periodically arranged sections may be fully n-doped or fully p-doped.

    Abstract: High density fiber interfaces for silicon photonics based integrated-optics products are provided via a system or device that includes: a prism configured to reflect, via a lensed reflecting surface, a plurality of optical signals between a first surface and a second surface at a non-normal angle of incidence; a photonic interposer including a plurality of grating couplers corresponding to the plurality of optical signals that are arranged in a two-dimensional array and that are optically connected directly to the first surface of the prism; and a plurality of optical fibers that are arranged in the two-dimensional array and that are optically connected directly to the second surface of the prism.
