An interposer apparatus for co-packaging an electronic integrated circuit and a photonic integrated circuit may include a dielectric substrate; an optical waveguide disposed on the dielectric substrate to optically couple the photonic integrated circuit disposed on one side of the dielectric substrate with at least one of another photonic integrated circuit disposed on the dielectric substrate or an optical device disposed on the dielectric substrate; and a metal interconnect disposed through the dielectric substrate to electrically couple the photonic integrated circuit disposed on the one side of the dielectric substrate with an electronic integrated circuit disposed on the other side of the dielectric substrate.

Co-packaging with silicon photonics hybrid planar lightwave circuit

Embodiments may relate to an optical modulator system. The optical modulator system may include a first photodiode to measure a first optical level at an output of a Mach-Zehnder modulator (MZM). The system may further include a second photodiode to measure a second optical level at a termination of the MZM. The system may further include a logic coupled with the first photodiode and the second photodiode, the logic to identify a modulator bias that minimizes the first optical level. Other embodiments may be described or claimed.

Optical modulator-based transmission control

Embodiments herein relate to photonic integrated circuits with an on-chip optical isolator. A photonic transmitter chip may include a laser and an on-chip isolator optically coupled with the laser that includes an optical waveguide having a section coupled with a magneto-optic liquid phase epitaxy grown garnet film. In some embodiments, a cladding may be coupled with the garnet film, the on-chip isolator may be arranged in a Mach-Zehnder interferometer configuration, the waveguide may include one or more polarization rotators, and/or the garnet film may be formed of a material from a rare-earth garnet family. Other embodiments may be described and/or claimed.

On-chip optical isolator

Embodiments herein relate to a photonic integrated circuit (PIC) with an on-chip optical isolator. The PIC may comprise a laser, a waveguide coupled with the laser, and a closed loop resonator coupled to the laser through the waveguide. A magneto-optical (MO) layer is over and in contact with the waveguide and the closed loop resonator. The closed loop resonator may comprise a first polarization rotator (PR) and a second PR. A light from the laser in transverse electric (TE) mode through the waveguide is rotated in the first PR to a light in transverse magnetic (TM) mode, and the light in TM mode is rotated in the second PR to light in TE mode. The isolator may further comprise a micro-heater over or along a side of the waveguide and separated from the closed loop resonator; and a feedback control loop connected to the closed loop resonator and the micro-heater.

Feedback controlled closed loop on-chip isolator

Apparatuses including integrated circuit (IC) optical assemblies and processes for operation of IC optical assemblies are disclosed herein. In some embodiments, the IC optical assemblies include a transmitter component to provide light output having a particular beam direction, and a transmitter driver component. The transmitter component includes a light source optically coupled to a plurality of waveguides, a plurality of gratings, and a plurality of phase tuners. The transmitter driver component causes a light provided by the light source to be centered at a particular wavelength and a particular phase to be induced by each phase tuner of the plurality of phase tuners on a respective waveguide of the plurality of waveguides, in accordance with a feedback signal, to generate the light output having the particular beam direction.
